I can see what you mean, but just because he's not a combination puncher doesn't necessarily mean his style is ugly. It's purely subjective, but I enjoy his style. Heavy on the knees, throws heavy punches and body kicks. And keeping your hands up is a sign of good training. I don't see how it could attribute to an "ugly style".
Yeah that's what it is the combinations and when he pushes people (physcially pushes them into the corner).
