WOW! Spidey is a lot shorter in real life! They must have made special sets for the movies so he'd look 6ft.
I am quite disappointed that he has chosen to set a bad example by not wearing his helmet. His heels are down nicely, but his leg is a bit forward of ideal, especially while riding the black horse and you can see daylight between his knees and horse. His upper body looks good though and it's nice to see someone looking up and forward.
This is an excellent example of a properly fitting rope halter/sidepull. I commend spidey for his knowledge of proper equipment adjustment.
(Cool pics by the way. Very well posed :) ).
