This is really fantastic. The animation and general style of it are impressive and inspiring. I think the ball could use a little squashing and stretching to give it a bit more life and oomph, though.

Wonderful job, sir

 Hmm yeah I think that may be a step in the right direction. The only problem I'm seeing with it is that the black parts on the chair and laptop and table legs are really hard to tell apart from the dark purple of the background. Making it brighter like that helps a little, but I think the best bet may be to make the chair and table brighter? Your call, really.

Either way, good work. I really like the octopus.

 It looks like the left arm and the left leg both go forward at the same time. it might look better if you made the left arm go forward when the right leg goes forward, like people run in life. also, the arms are pretty short.

besides that it looks good, especially the leg motion

 this looks really good, but i agree with the others about the shading in the sky. It could use a little more smoothing and variation. The different areas of color in the sky aren't integrated quite enough yet, I would say. I can see that the method would work because the parts close to the moon look great.

anyhow good luck if you revisit this and in your future pixels, man

 it's a little messy and the hair strikes me as sort of strange but i like it a lot. cool stuff, man

 This is pretty cool

It might benefit from some extra brightness and had a little more contrast, though. It's kind of hard to see the laptop and chair, which makes it slightly unreadable

 That's very beautifully done

 Yessir it is meant to be a monocle

Yeah you're right the monocle string-chain-thing and shoulders (and probably hat) should definitely move, at least a little.

As for the eye patch, it's actually just painted onto the metal of his face

 Thanks

yeah, the jolly roger on the ship's sail isn't very noticeable. I agree that it could use some sort of stronger indication that it's a pirate ship.

I see what you mean about the unbalanced composition. Thanks for mentioning it, I'll be sure to focus more on composition in later pieces.

 thanks! yeah it is very scribbly. I tend to pixelscribble a lot

 haha that's brilliant.

The only problem I see with it is that when he rises back up after smacking his face against the ground, his foot is not in front of him enough for it to propel him up without launching him forward. If his foot leads him by a bit before his leg stretches out, it may look a little more ...correct? 

Anyway great job

 hehe, sillywalks. great job!
