Racing game level concept art

This concept art is for a personnal project, it is meant to be the first course you take on, and is designed arround a crescendo, you start in the nature, then take on the race in a traditional village (which is meant to introduce you to turning and drifing), until you jump above the river to finally end up in a futuristic metropolis. I did it in 2 hours and it is not meant to look perfect, it was just to get the feel, colors and atmosphere of the level.
