Ford Sierra Rs 500

Nice!
The first thing that strikes me about your drawing is that the car fills the picture plane. My only gripe about the composition is that the front bumper touches the edge of the page. I would back it off and give it more space there, even if it means drawing the car a bit smaller.
You got a great return here on your ten hour investment. Your proportions look good, and you did a fine job on the foreshortening. You certainly did a great job of capturing the lines and character of the car.
You have a nice range of values here, though the car itself is rather light. Perhaps that is because it is a white car, but i would like to see a wider range of middle values in order to show the planes and contours of the body next time.
The wheels are well proportioned and fit the car very well. The shadow under the car does a good job of nailing the car to the paper.
It's a very good piece of work! <img src="e.deviantart.net/emoticons/c/c…" width="20" height="20" alt="" title="Clap"/>
