good work using the audi paint donor to fit an Evo X
The windshied looks weird because it should be transparent so you can see the interior.
Also your brushing is very patchy You can maybe make it smooth by using the smudge tool, or very lightly brush more layers of colour ontop to blend the patches together, if you have time, try to read this tutorial, it will help alot
