it's... squashy!
hold SHIFT or CTRL while resizing, or else you will have distorted renders.
in this case looks how extremely wide he looks, and the upper part of the head should be a circle not an oval hehe. that's how you are able to see weither a resize went good or not, once a circle becomes misshaped you know you have to do something about it. ( unless you meant it for it to be that way. )
