The skin around the eyes and mouth...could it have been from a poor fiting bridle with blinders? Maybe he has sensitive skin...either way bare skin should get some sunscreen on it because I couldnt imagine how bad it would hurt to have sunburned eyes. As far as his legs go...yikes...those pasterns look bad. I suppose if he is sound, its not a big deal. I just cant see him staying sound into his later years. The length and angle is, as smrobs said, a deformity. Im not getting down on your boy...he is very cute and has that 'ive got personality' look to him...those legs just look off.
