This looks really good! your rendering is nice and you seem to have a good understanding of anatomy. I also like the composition of this piece and how you have your characters looking so fluid and lively with their colors, facial expression, and movement. The posters and random items really brings their surroundings to life and makes this piece look like something out of an actual cartoon or animation, instead of having them look flat and lifeless. The only problem I have is the bright neon green of the room which kind of makes the one character with white hair blend into the background. Other than that, keep up the good work!
