I'm going to actually contribute. Your shading and contrast is mediocre at best. You seriously need to improve that if you even want to consider turning that "thing" into the server. You're over looking a lot of small details as well. Things like car windows and the police sirens are done very poorly and need shading (I don't even see windows btw). Also, if you were curious pillow shading is not shading. I recommend seeking some graphics tutorials online for guidance on how to properly shade and add reflections, basic stuff like that. If you were to put that car into the game at it's current state you wouldn't even be able to depict the different colors you tried to implement, USE MORE CONTRAST. Learn from my words because at this moment your car doesn't even compete with the current one.
