The pasterns are fine. I suspect there is not a lot of foot to work with and that may be part of the foot issue. Please put bell boots on while you are waiting to get the feet squared away. If he steps on or catches the overhang on those shoes the mess will get worse.
He is pretty nice. I wish there was more bone in his front cannons. He is also standing a bit sickle hocked. I am not sure if that is because he IS sickle hocked or if it is because his hind heels are so under run. He almost looks like his toes are elevated.. but I suspect he is really sickle hocked.
He has NICE roomy hocks and they are nice and low as are his knees. His shoulder is also nice. Maybe a bit steep but his front leg is not plumb so that may be an illusion. His coupling is a bit long and his neck is 'upside down.' He is new to you so you will work to fix that.
I like your horse quite a lot. With good feed (check for ulcers) and good farrier work and property training I think he is going to come around nicely for you!
