The legs in 1 are a lot better and telegraph his personality better.
I'm really not sure what his left arm is doing. The arm on the hip works quite well with the pose but the arm that's extended doesn't appear to be doing anything meaningful, although I suppose it depends on what you do with his fingers.
I would recommend looking at when he appears in the manga/anime and see how he usually holds himself, for some ideas on what to do with that arm.
His pants should end a bit lower and his 'shirt' should be shorter and end higher, as well as have its own shape independent of the body as though it was starched.
The arm on the hip almost looks like it's seen from a complete side view, the circular band running around the armpit and shoulder should be rotated more towards a 3/4 view.
His hair is also too horizontal on the lower half of the back of his head, and the hair on the top of his head should be longer and point upwards more. His hair should be just under 1 face tall.
