Your art is so good and I really like your style! I was wondering, how do you draw backgrounds so well?
You probably mean that one background in the most recent part of the 3 months au comic which the making of was quite of a journey so im gonna explain it step by step
step 1. Pretend that you know what you're doing and practice (for example this background that I drew over a year ago for RinRee's comic "Broken Bonds" (the characters were drawn by her)), gain some experience
step 2. Get a minecraft reference (if you suck at perspective like me)
step 3. fail miserably
step 4. get more references
step 5. figure out what you did wrong, study (for ex. your references), practice some more (i cant show because my practice were other backgrounds for the 3 months au comic)
in my case what i did wrong was lack of warm up (the last time i drew an actual background was few months ago which is WAY TOO LONG), making it not look like an actual train and in general making the room look too organized and empty. Mikey is a chaotic and artistic soul so it's obvious that he'd have a mess in his room (it's important to think about what a character would have in their room, ex. art supplies, sticky notes/stickers, junk, posters etc)
step 6. try again
BONUS: I genuinely enjoy making backgrounds, so it's easier for me to stay patient and pay the attention to them that they need! :]
