At first glance he looks like one that could make a "good 'ol reliable gelding". Not built the best and won't be your prime athlete, but surely could get the job done.
Appears to toe in in the back and possibly the front (can't really tell from this view though--and he needs a good trim). He's tied in at the knee. Built downhill. Has a plain head and thick throatlatch. Neck ties in a little low for my taste but it's a good length. For a 3 year old, he should be fitter. Needs topline muscling. Back is nice and short, but a little roachy looking (that's likely due to lack of topline conditioning).
For a gelding I wouldn't be too dang concerned about anything. If his eye tells me anything he'll make a nice kind boy.
