Really nice work on the side c&p work - it looks great.

The only problem I see is that the whole car seems to be tilted down towards the front. Almost like there's someone sitting on the hood and pushing the front down.

Keep up the good work though!

Update. Used the tires from the E46 wheel donor posted and used the ccw's from the other. Not too shabby. Completed more paint work from the C-pillar, roof, and some on the front and restored the lights on the front grille. Looked weird on the other side to me

New rims are looking much better, there was some slight perspective issues with the last ones. Paints looking good, you just now need to extend the bottom of the front bar further along the drivers side, bring that background through the windshield and loose the green hue on the glass too.. I guess you already know of those small things that need attention though. Also I'd recommend straightening the chrome pieces in the grille and you'll need to adjust the colorization of front bumper lower you added in slightly. Keep at it!

looks nice
Mark already said about the tips to do so follow them is my advice
