He looks a little green, which is OK, I would get him on full feed and start working on him. As for the dung balls on him, I would start soaking them with a little WD40 and try to work them off of him, I am guessing the weather is keeping you from rinsing him. If you can get them off of him now you will be ahead when you can start rinsing. I do not think he is high flanked just young, he looks to be balanced and have potential. He does appear to be gentle, and for me that always a benefit.
Good luck and have fun.
