that front wing and sideskirt are looking pretty awesome mate
a bit of advice (which im gunna include in my next tutorial) when you brush a car, you will never see the paint go from dark colour straight to white. you might get a patch of dark, then white shine, but the white shine will have a bright blue glare around it for example. Youll only get a white part on the car where the sun is strongest, and because of the strength of the sun, it brightens the paint around where it hits too
might seem a bit confusing, but ill have diagrams in my tut. another thing is, reflections never fade. if you look in a mirror, the wall behind you wont be blurry or faded will it? its the same principle, they will only warp out of sight in the body of the car.
keep it up, ill be watching
