OK well here is what i think should be fixed if you are looking for new poses
venom-ive never read a single comic, but that figure always looked cooler to me if he had his legs bent kinda like spiderman when he was swinging
iron fist-again, never read a comic, but he looks cooler in a crouching kung fu pose
carnage-does he even have webbing?
movie goblin-make him crouching on his glider, looks cooler
storm-it looks alot better if you put one foot on one of the outside pegs of the storm, and one foot on the lower inside peg of the storm
youve got an odd choice or two on your wall, and if anybody should be on a wall/in flight, it should be human torch, its tough to get a good natural pose with his base, but it looks good when you figure it out
id put nightcrawler in more of a crouching spiderman type pose
id put bishop in a ready to fight stance with his guns drawn
id put magneto on a flight stand with one hand extended
and if you are gonna be crunched for space, take the green goblin and hobgoblin and use fishing string to hang them from the ceiling of a shelf to look like they are in flight, i noticed you had tacks on the shelf, might as well use them
kudos on the ghost rider pose, it looks really cool
and dr doom looks silly,id make one arm at his side and one up in the air
and battle ravaged spidey would look cooler laying down in from of rhino or lizard, or fighting them
