very nice and coll

 

Ok, thx to all, lemme see, I just need to make the shirt movement a bit more realistic and his head movement more elastic.....uhm I don't like bouncing things but I will try, yes I should retouch the fists size in the middle part, didn't finded out that when making it T_T
And reduce the arm pause...ok...starting to work!

 I really like most of the animation, think the body needs a bit of a twist tho to go along with the amount of swing youve got going on in the arms. I agree that the pause in the arm movement shoul be shortned, it kinda looks like hes skateing with it pausing for that long. Nice overall tho.

The strong movement of his body versus the non-movement of his head looks stiff. His shirt and it's contents seem like a neat package -- the shirt doesn't wave much, and is shaded like it is completely filled by his body.
To change that, you could modify the shading so that the highlights point away from the inner edge of the shirt rather than their current pointing towards the edge of the shirt.

one of the frames when his hair sways forward has a 'lumpy' movement of the far fist. Usually I find that when this happens to me, the part is not moving out enough. In this case the fist needs to move right a bit and up maybe 1 pixel.

There's also a fist size issue with the near fist.. it gets bigger and smaller.
Mainly the middle frames concern me; the 'fully extended' and 'fully retracted' frames seem workable. The fists are not.. long enough in these frames so they look childish.

The actual animation motion is great. It reminds me of an ancient CPC game 'Countdown'. I agree that the arm stop looks stiff and should probably go.

I dont like the fact that the arms move but the body doesn't, but the legs movemest is almost perfect

I was trying to make some different kind of movements since everyone make their loops look alike, do you think it will be better with out the stop?
(his arms will continue to move endlessy    )

Cool animation, but I don't like that stop that his arms does on frame before his right foot step on the ground.
