I agree, the second one is the more complete one, but the black around the jacket doesn't match with the rest of the sprite. There's no outline on the head, and the outline on the pants and shoes is only slightly darker then the jeans.
As for the first one...
His left arm is ultra tiny and thin, and... I'm assuming he's holding a butcher knife? It's hard to tell since it has a slightly curved guard at the top of the handle (it's not actually a guard but the problem is at that point.) The scarf kind of... grows, as the animation goes on. The middle puffs up a lot but the end doesn't shrink to compensate. He's also leaned a bit too far back, that's sort of an impossible posture to pull off. Also consider his chest should expand as he breathes in as well. And why doesn't his hair sway in the breeze as well?
That's all I can see atm.
