Hard to tell from the pictures but he looks real strait in the rear, a good rule when picking a calf is start at the feet, watch them walk, if they have issues walking it will only get worse as they put on weight. Standing, his topline looks fine but next to the Char calf he does appear to be narrow made, would like to see more width in his stance, all his toes point forward and that is a good thing. If he is already yours, then I would say pour the feed to him and make sure he gets out and moves everyday and give him a good joint supplement to keep him as sound as you can, if he is not yours yet you might look some more.
