I was surprised to see how good his posing was... and he's really just beginning to learn how to do it properly.
Needs more muscle. We don't see the legs, which I suspect are a major weakness (the calves are, surely).
If he comes in in flawless condition--say, at 165 or 170... or lower? (he's at 200 in the video)--he might be able to do well. But not having seen the wheels, it's hard to say.
Alex looks very good already (from what I've seen in old photos), and is slim but well-proportioned, lean and without obvious failings. Billy has a hard road ahead of him. But his upcoming SHOW is what will really test him.
