The most of my drawings I render using a linart to draw the basic lines of the car, and all tuning features are my ideas combined with things what I saw (here on dA, on internet, on the street...) I don't usually re-draw a photo, because I want to make a concept of tuned version of the car I draw Thanks.
So cool. The design of the front clip is so unique. I've never seen so many curves in one location and work for it. I have to admit though, it's weird that it looks crowded there but the rest of the car looks simple in comparison.
