You do look too stretched out in that picture. Your arms appear to be pretty straight (instead of moderately bent at the elbows so that you can use them to absorb jolts). If you accept the KOPS rule (the front of the knee directly above the pedal axle when the pedal is at the 3 o'clock position), you appear to be sitting too far back.

Reason: Corrected typo regarding KOPS rule.
