Carl1, based on what I can glean from the poor pictures, I would agree with others who've said your seat looks too low, and I would also say it looks like you could use a longer stem if not a larger frame with longer top tube, and presuming you'd like to get a more aero position, a lower bar position.
But yeah, you look a little scrunched up, which I'd think that while it may seem comfy now, will reveal limitations as you ride more aggressively. One can ride anything, but they start putting down real power, over long distances, and want to do things like attack climbs or sprint all-out, the situation changes dramatically.
