If you aren't going to shave it all off again, I would suggest going over it with clippers to make it look neater. Keep the back by the withers shorter, and the top by his bridle path shorter, so it doesn't leap up into big ol' mohawk. Like FAM's picture of that last horse, it starts short, gets long, then short again. Of course, that's just personal preference. =P
You're the first person here that has called me by my proper nickname! Most people at school refer to me as FAM.
