you need to smooth the mask or wherever you grabbed the car from. the rear quarter panel/bumper have somethin funky goin on too. why are you doin a white car on a white background? its washing out and you cant tell what starts where
Yeah, you've got reflections in it. Try to match the color on the rear 1/4, and it looks like you used the magic wand to select the background, which also selected part of the hood and deleted it too.
