Prime Battle

Don't look at the title, I just choose the names of the songs I listen, I don't even know anymore if they fit the pic sometimes.
But yeah, I never was good at challenges, but decided to try out this one, because it's like a double challenge for me - drawing AND uh, not forgetting or being lazy. I mean, I never did any challenges, text or drawing, because I always was too lazy to continue them after first-second day.
But I rewatched Gravity Falls last two days (and goddammit I'm doing it again right now), and then I found a 20 Day challenge. I totally will not do some of them, like, 2 or 3, but whatever.
I wanted to start this challenge with a cool pic but then I failed, I guess this is why I never will be an illustrator, I just can't work with colours and editing, I mean, look, can you see Bill's Hand ot leg from first glance because I doubt it and I could do nothing about it I suck at painting I suck at backgounds I suck at drawing trees I just suck. Yeah.
So, this was day one: favourite character.
Do you see where did I cheat
