If it hadn't been a car, it might've been a little better. Cars are just one of those things that have.. almost step-by-step guidelines even. There are specific ways to shade a car, in the design industry. Certain angles always work the best. Certain angles for the wheels are also always more effective to make the image more fun to look at. I was surprised he didn't use the standard window shading technique, really. Because... even if it's THE standard, I think it might even look better. It's the standard for a reason, right?
So, yeah. If you can draw a car, you can draw a car. There's not much more to it. There are no ways to make a car more dynamic. There are no ways to make it interact with something else in an exciting way (unless you make it crash and explode, but that's something entirely different, then). A car is just a car. Let me try that two or three times, and I bet I can give you the same result. Probably quicker, judging by how long he messed around trying to get those curves right. (That WOULD have been better with vectors.)
Also, the more praise something gets, the less I automatically like it, and I bet that thing there gets a ton of praise from people who can't even tell apart the flaws in his process... and his nickname.
