Not bad! At the lower levels rhythm and pace is everything. As long as you can keep your horse on a steady (and correct) rhythm, nail the distances and get the changes, your horse has a chance of doing ok, even if he's not the best mover. On the flat I'd shorten up those reins and start to teach him to round a little more, get more on the bit. Try and open up his stride. That will help out a smidge in a hack class.
Have you done any gymnastics with this guy? They can help tremendously with teaching a horse to snap up his front legs. He's a little sloppy there. The good thing is he looks like he makes a little effort to bascule over the jump. A properly set ground line can also help a horse out quite a bit.
