NeoStrider the animation is fluid, there's lots of preemptive movement, and some good timing in your pauses. there's really nothing that i believe needs fixed or changed, but it does kinda bug me a little that before pressing the button he looks around to see if anyone's there, and even after looking green dude seems to appear anyway. maybe it's just cause the environment seems void of anything. it's just orange guy and the button. maybe you could show a pov (point of view) shot coming from green guy, and he's hiding behind some box or around a corner and just barely glimpsing orange dude during the time orange dude is looking around?
another thought that comes to mind that might enhance the animation is... what if when he lands after swinging his landing takes him below the display where the button is (so he's totally out of view), and for a while all we see is nothing, then slowly his eyes are revealed, looking at the button, then his whole head appears, peering around it, and THEN he gets up to look around? i dunno about you, but i think i would inspect a button on a pedestal for some kind of sign before just looking around for witnesses and pressing it. just a thought.
either way, the animation that you have is rather well done, both with fluid movement and good timing.
oh ok another random idea. easy thing to change. put the words 'push me' on the button. fantastic.
