I don't know what your plans are for him.. But as far as health, make sure you kep up on your wormings, and that you keep a good healthy diet for him.. Other then that, he looks fine (nothing sticks out as far as serious worries). He does have quite a haybelly, but nothing I would be too concerned about, unless doing serious shows.
See how he turns out as he starts going into his yearling phase. There are still going to be some radical changes he will make through this point in his life!
