Awesome, Mustang. Looks pretty nice. I like the third and fourth one, maybe the fourth a bit more. Maybe a little work around the render, it looks a little weird. Great job though.
v3 is the best IMO. One thing I don't like is the pattern. It's too repetitive. Also, the lighting on the focal is a bit messed up. BG is a bit bland (cause of the pattern) but I like the effects you used. Nice job.
