nice choice, i understand that U're going to make Barricade Mustang varsion, right? Don't forget the famous sign on the back of the car and try to use the forum link from imageshack so that small thumbnail will appear in Your post. Good lusk
I think the upper front needs to curve out a bit more, headlights look really tall too. Though you may not finish it for the contest, I hope you will continue at it, it looks like a good start, just needs some tweaking.
