You are so proud of your horse so I hope you will not feel bad to open yourself up to critiqueing. Star has rather crooked front legs. He is over at the knee on his left front and the right front is both over at the knee and a little tied in (the main tendon along the canon bone doesn't attach in a straight line but rather is kind of tucked in under the knee).
His pasterns are very upright on all legs so he will be a bit of a rough ride, maybe. His hind end is nicely sloped and muscled. He has a very nice , deep chest which will give him good endurance.
He is no doubt a really sweet guy and will give you his all. Congratulations!
