Not only are the pictures too small, but the angles and presentation of the horse are also not good for critiquing. Some may post critiques of what they see here, but it won't be a fair evaluation. Would it be possible for you to retake the pictures with the horse stood up and the cameraman taking the shots from the horse's level? Don't forget to post the new pictures larger, too. Thanks!
There should be settings on your camera for pixels/size/clarity etc...I never know exactly where lol but take a peak under Settings or Options!
You want to square him up, maybe a little stretch, kneel down on the ground and get pictures of him directly from the side down on his level. Head forward and either up, or arched out and forward. It does help to get a second person while you take the pics!
I agree these pics of him are bad to ask conformation on...he looks like he is much better than these pics show!
I would be glad to give you an idea of what I see, but as mininik and others said, the pictures just don't show what we need to, to be able to give a fair critique (which, really, from photos, should just be a guideline).
