Of the pictures you sent me this is my favorite. I like the characters, they each have their own interesting pose and expression, and the spacing and framing is really well done. I'd recommend trying out some shading tricks now, you seem ready for it, in a picture like this with a pure black background, the best way to make that work in your favor is to shade the characters as if they're in a dark room. Looking good, keep it up! Thanks for sharing
