Alright, so, I'm trying to help out my friends by drawing graffiti art for the background of an expansion to a game they're making, and I made this (pic related) in Paint.net. I'll post another pic of something that's being used in the background already. I intend on making more stuff for them similar to this and would like feedback on how I can make my drawings look better.
Here's something already being used in the game
