There are two other classic poses that would be relatively easy to do with this kit.
1) Spidey suspended upside down on a strand of webbing. You just need to repose the hands and feet.
2) Spidey in mid swing. Repose the knees so his legs are straight out. Repose the hands to hold a strand of webbing. Run a metal rod up the middle of the webbing to susped him in mid air. You could also use this pose to have him leaping over an object , like a chimney.
