A bit messy.  Still pretty cool though! 

 Nahh, I like that look actually. It was intended to look like a cartoon. 

 That definitely helps, but the black lines inside the shape still seems totally unessecary.

 I was considering adding the black bg, but if I leave it transparent, AA on the outside would look bad against certain themes. There is currently AA on the inside, so the jagginess comes from the outline on the outside, and could be remedied with a black background. 

 The way the highlight in the circle bends around the top of the circle makes it look like you're shading a sphere. It's just a circle on a wrapper, around a cylinder and should be shaded the same as the rest of the cylinder, not a sphere attached to it.

I think this would benefit fromm removing the black outline, or some AA.

 Cylinder, why? 

is it being reflected off a sphere or a cylinder?

 As for the circle, the reflection is supposed to make it look more metallic. Either way, even if it's not realistic at all, I like the playfulness of the bouncy highlight. 

The lines could definitely use some work, and I'll probably work on them soon. Thanks for the feedback!

looks fine to me besides the circle

The black lines feel too jagged to me. Also, the highlight on the circle is odd to me since I believe it's just a label wrapped around a cylinder, so it shouldn't be shaded like a sphere.

It has potential, and I like the direction of it, just needs more to take it to the next level!

I dunno, I was legitimately proud of this piece. Perhaps because it is my first animation where each frame was drawn individually (no copy-paste), it looks messy/unfinished, and if so, that will be fixed with practice. 

 This piece misses a bit of soul, friend...sorry! I think in some way that's what jalonso is trying to say, it seems to be missing effort. And you are so capable...

 haha. I updated it (some AA, shading, etc.). Is it any better? 

Well I just would have liked to see the pixel level precision all your work shows and I don't just mean AAing and stuff like that and its difficult to express other than to say that if I saw this on its own I would never think you made it. I don't even know if your intention was a 'pop art' play but perhaps bumping up the style would help overall. You inately understand cell-shading and this could perhaps use that? I really don't know what to say and don't wish to sway your creativity...I wish this was more saucy and less soupy 

 Sure, it makes sense. I know what you are referring to in theory, I just don't get what you think should be improved in this particular piece (I don't mean to be saucy, I just want to know if you have any specific suggestions for this piece). 

The animation, compostion and idea are all there. In the forum thread this looked very promising and still does.

Simplicity is never a problem for me and sometimes simple is the best choice. Here because of the Pop Art association simple is probably the smartest design choice.

I only refer to pixelart technique, line quality and perhaps even palette. Even if you were trying something new or experimenting there is no good reason to forego the skill level you have when making pixelart.

Does this make any sense?

 Do you say so because the animation is poor, or because the soup is very simple?

 Because you can pixel so well I find this something of a fail for you. Knowing your skill level this seems unfinished and uncared for.
