No bad Walks! Try putting some movement in those checks, and like earache says fade them out into the paintwork.
Id personally rotate those stars on your number a tad as well as they look a little copy and pasted.
Apart from that mate it looks good, alwats remember we have all started somewhere! Keep looking for new fonts so that you can make your own graphics/decals/artwork as a custom RCE ( for example ) is better than one everyone has been caught using at some point ( myself incl) I personally like Olive antique, with a arched look, and some nice colour fades, always look at Brian Evans colours his are always spot on fantastic!
Anyway enough rubbish lol
