Nice and low and flat back, but your seat is too high, really, your back leg (the one at 6 o’clock) appears to be fully extended. You need some bend in that knee. If you do have some, post a different pic showing the front leg at 6 o’clock.
Elbows behind your ears, so that’s ok there, although they could be at 90deg instead of, what, 105-110…? (i.e.: shorten the stem up maybe)
I’m not the fit expert, but that’s what look off to me.
Any time you post a position pick, make sure that your leg closest to the camera is at 6 O’clcock. That way we can see what you leg is doing.
It looks good though. Maybe one of the better position critiques that I’ve seen on this site.
I think it looks quite good. It’s probably even better than this (which is pretty darn good):

You aren’t Jens from CSC are you?
Not the Jens from CSC. Here is a pic of ST’s Jens:
this one is almost 6 o’clock…
my seat is not too high, or at least it feels better there than lower.
shorter stem: I don’t think so either, as I tend to hold the bars at the far end.
I did ironman zurich in july with my front end about 2-3cm lower and saddle 3cm forward, I had problems holding the position the last 60km.
I dont have a powermeter so i can’t tell for sure, but this setup doesn’t feel slower at all, I climb better and descend better with the saddle more backwards (3cm behind BB and 70cm tall).
I have a tendency to sit on the tip, but I,ve found that that is independent of fore-aft or height of saddle and also of reach.
jens, are you faster in the superman position than in the one oyu tested at the windtunnel?? do you raise your bars when you reach forward?? If you don’t, you get lower, don’t you??

I can’t see the pics, is it just me…?
He’s exceeded the bandwidth form his host. I saw them earlier and his seat is too high! 
yeah, it’s a bandwidth problem… i can see them now
Looks good…but your need you hips rotated forward. The “curve” is too low on your back. Look at the CSC pix above, the curve is in the middle of this back and it’s pretty clear to see the difference in hip rotatation. Other riders it will be higher. Lance doesn’t count b/c his back is double-jointed.
