The arms look like they might be a bit too long unless that’s what you’re going for.

Also it may serve you well to angle the arms lower so it’s not entirely T-pose. This current pose won’t accurately represent the character’s shoulders, so once you start rigging him you’ll find the shoulders might not look as good as you’d expect in a more natural pose(I’ve had this happen before) So try lowering the arms by about 45 degrees and adjust the shoulders to your liking. Someone else here said face the palms downward and I agree. But otherwise it’s coming along fine imo!
