It’s such a good feeling when you finally accomplish something you’ve wanted to do for a long time, right! It’s looking good!
Since you are going for realism, I think the bullet holes could use a bit more of that, as could the dirt. The painted stripes shouldn’t go over the awning frame and wipers – oh, and the wipers should rest on the windshield.
I really like the way you placed it in the landscape, it looks very natural.
