I haven't read any of the other replies, so I may be repeating things here. Apologies in advance if I am.
Is that your normal riding head position? I'm thinking not. Anyway, your back is very rounded, which may be from the way you're gripping the aero's, or that your head is down. It's hard to do these things unless you give "action" shots. Your upper arm to torso angle is pretty open, which suggests that the top tube and stem combo is on the long side, but you may grip farther back when riding, closing that, and maybe even flatteneing the back. As I said, hard to tell from stationary photos.
So I've probable given you nothing. Sorry.
