Kiserm, why do you slide forward on the saddle so much when you go into the drops? You were thoroughly on the rivet, rather than sitting with your sit bones supported. Perhaps your handlebars are too low?
I think your leg extension is good.
You do look crowded in the drops, knees are at or ahead of your elbows. How is it if you keep you butt back, with sitbones still on the sweet spot of the saddle?
