So first I know what problems I made with this piece. I did not establish a good vanishing point. This explains why the street looks as distorted as it does. I need to tighten up some of the line work, this I am aware of too. But I want some better coloring/lighting advice How can I improve these things? Any suggestions?

This scene was inspired by a conversation I had with a friend. We were going back and forth taking different celebrities, politicians, reporters, etc and anthropomorphizing them. The two you see here are Chris Tucker the squirrel to the left and Jackie Chan the weasel to the right. in one of the Rush Hour films there is a scene where they are swinging towards a truck, Chris screams like a girl and Jackie kicks him and runs along the side of the truck. Aside from the line work, what colors/lighting tips can I be given?
