I can explain "width" further. I think it's an incredibly important if increasingly overlooked aspect of current instruction, Butch Harmon excluded.
Gulbis camera angle looks to be on the ground looking up and will make the hands seem to be lower than they actually are. The other camera angle appears to be some where about the waist, so not really the best comparison.
Couldn't you get more width by getting the hands further behind also, not just up?
