Hey tknaspontana
Good attempt with the chop, but I think you are doing a bit too much, as I can see alot of simple mistakes. To help you out, heres a few things I can see
1: The shadow is all wrong, you should use the shape from the original image as a rough outline
2: The paint is looking a bit flat, maybe using a soft size brush on 10% opacity you can brush some highlights to make the paint shiny
3:when the image was flipped, the Pugeot badge wasn't flipped the right side
4: the window is very see through/ transparent, I used the Pen tool to select an area of the window and then brushed with a big size white brush to make a window.
Hope this helps

Cheers
J
