Nitpick Number Thirteen for Nitpick November:
I feel like the Xiao Long/Rose/Branwens don't really look related.
Summer and Ruby look nearly identical but for haircut and cape color, but they don't look like mother daughter, they look like twins, or a 'this is me now this was me a year ago when I was happy' thing.
(Granted, the change to Ruby's hair made her look slightly more varied, but not enough.)
Meanwhile Raven and Yang look like someone just took Yang and played around with a color wheel, but again, they sure as heck don't really look related.
And while Raven and Qrow can pass as related, she looks more like his daughter than his twin sister. Meanwhile, Tai and Ruby have like, not one thing in common in terms of their looks, and Yang and Qrow don't really look related either, though them looking related is slightly less important than say Tai and Ruby or Raven and Yang. The only people in that family who look like they could be blood related are Tai and Yang, and even then, her hair is a totally different shade and her eyes are a different color. And yeah, there's no way I would've ever even sort of guessed that Yang and Ruby were sisters just by looking at them, and I get that they have different moms but they are still blood related through Tai.
Now, I do know that not everyone in a family has the exact same hair color or eye color. But it's kind of hard to get across facial family resemblance in this kind of art media, which is why people tend to rely on families having the same kind of color scheme in non-live action and it's why we get things like this
Or the old trick of splitting the features you want the kid to have between parents.
But instead, it really feels like they designed four characters without thought to whether or not they actually looked similar (Ruby, Yang, Qrow, and Tai) and then when it came time to design the moms, they just said 'fuck it' and used a clone of one of the girls and a clone with a different color scheme for the other one.
Here are my suggestions for ways they could've been designed to maybe look even slightly more like family.
They could've given Ruby blonde hair with red tips instead of black. I know a lot of people kinda consider the OG designs of the Ruby girls or at least their color schemes to be absolutely sacred, but I... Don't. Unlike her silver eyes, Ruby's hair isn't an actual plot point, it's as aesthetic and not technically necessary as her combat skirt. And I already think that the designers could've done more to make Team RWBY look more cohesive because everyone's got this very red-and-monotones color scheme (with only slight additions of color like Blake's tights fading into purple or Weiss's blue eyes) until you get to Yang who is all yellow-brown, and if Ruby had more yellow-gold to her own design, it'd feel a bit more complimentary. Plus, I kind of think blonde Ruby is a cute concept.
Tai could've had purple eyes.
Tai could've had silver eyes. I've been very clear that I think Summer was unimportant for like six seasons as anything other than a tool to add onto Yang and Ruby's characters, and then the show didn't do a great job of making her important when we randomly started being told to care about her in what I can only assume is an attempt to hook the audience and/or pad out the running time of the show, so why not have Summer continue to be a dead mom trope and Tai can be a retired former SEW? Maria is already there to alert the audience that "Silver Eyed Warriors are in so much danger you guys!" Why can't we have this character that says "but some of them make it" as a hopeful contrast?
Raven could've had purple eyes. I personally headcanon for my own fics that Raven did once have purple eyes that turned red when she got mad like Yang's did, and they just kind of 'got stuck' on red mood not long before she deserted, which... Might be a dumb headcanon but I like it. XD But yeah, the show could've just had her have purple eyes, to make her look a bit more related to Yang. This would make her also look more similar to Yang in the model she has, though, so I'd prefer for this to go hand in hand with my next suggestion, which is...
Raven could've been taller and her face could've been thinner, to make her look more like Qrow and (more importantly) more like an adult, and/or her hair could've been graying like his is.
If Ruby stays exactly as she is, then maybe possibly they could've had her dye her hair. "Oh but hair dye might be hard to supply on the road-" If they never run out of food and are shown hunting or restocking on the road, I feel like they can find hair dye. If they never run out of dust, she can get hair dye. If Jaune can somehow manage to never damage his sweatshirt, Ruby can manage to get her hands on some hair dye. Also, I don't hate the concept of showing fictional characters with roots in their dyed hair, it adds some relatability and humany feelings to them. It could've been a volume four thing, and she has to re-dye her hair when they get to Mistral. Ruby is supposed to have 'really into goth stuff' vibes, right? So why can't she dye her hair black on the regular like a lot of people who are really into goth stuff do?
I really don't know, I just think it's weird that they don't really look related.
