Hey it looks cool…there’s already a lot of work but i really feel like the scene is far from finished…i am not fan of the all orange look but perhaps it’s a matter of taste…at least more contrast in the lighting would be cool i think.
Your cars are cool 
How many props did you do atm for the scene?
Perhaps, less ‘hero’ props and more modular props would help you a lot for filling some empty spaces…my two cents…
Keep up the nice work
