I finally did it! It turned out to be 12 hours instead of 10, but I did a little family tree:
Notice my atttempt at a sideburn? I just wanted to note that when facial hair is outlined, it means the person actively keeps it neat and trimmed. When it's a spiky shape is means he forgot to shave. Anyways, a little explanation of some of the details:
•Vili looks like Bor, but the hair is straighter and his eyes are blue like Bestla's. The nose is more of a mix between his parents', though it leans more towards his mother's.
•Ve looks like Bestla, with the same nose, hair texture and just a bit darker on colour (here it's gray because he's older, but he used to be blond). The eyes are Bor's, but more hazel than brown.
•Odin is more like a mix between the two. His hair type and nose and from his father, but the eye, hair and skin colour are from his mother, just a bit washed out from doing a lot of magic. Btw, Odin's ear is more of a genetic mutation that a lot of his children inherited, that's why it's considered an æsir-specific feature.
•I don't have much to say about the parents themselves, I just designed them around the traits I gave Odin. I'm disappointed that Bor's white hairs and their wrinkles aren't as visible as I thought, but it'll do.
As for their relationship towards Loki and Odin, I haven't thought about that too much. Since there's not much information about Bor, nothing stops me from saying I think he doesn't really appreciate Odin, he would have rathered any of his two had taken the throne of Asgard. Why? No idea, he just gives me that vibe. Homophobia maybe, idk.
For the brothers, it's a bit more complicated. I hadn't even considered Loki knew Odin's family, but then I remembered he travelled with at least one of them that time they couldn't cook a cow (I'm writing all of this from memory). So they know each other, but I don't think there's a great friendship between them. And for Odin, at first I thought they would get along because they killed Ymir together and all that, but there’s also this story where Odin was long for so long everyone thought him dead and his brothers took his throne and married his wife (I think it was mentioned in Lokasenna??), so that kinda breaks their trust.
Also I wanted to draw them as children but it'll take a while.
