This is really a good chop, and with good taste I must say.
Nest time try to work a bit more on the shadow, cuz to the left it should've lost some definition, I mean it should be more difuse. the painting looks good, I can tell you have the notion of how the car should reflect the things around it. and you could've worked i bit on the front, making it more glossy and darker.
Next time try to do something on the interior, and post your progress in the wip section so other artist can help you improve

Once again I think you deserve promotion. Keep it up
