Looking good! The angle of his head demands that his left (our right) arm be partially obscured by his body. This helps create clear levels of depth. The way you have it now instantly flattens him to a single plane.

Also, I think this could really benefit from a healthy dose of antialiasing, or AA. You have a thick outline, which is fine, but then you have a narrow line of bright pixels surrounding it. This accentuates the jaggedness of the line, the opposite of what you'd generally want. Manual antialiasing is pretty advanced and can be tricky, but you gotta learn sometime eh?

I also would tone down the saturation of your colors, and try to move toward purples for your darks. Shifting hue (color; red, green, blue, etc.) in addition to value (lightness) is a common and sensible approach to coloring. It just generally makes things look more interesting, and parallels real life, for the most part.

ain't this based on these Pon and Zi comics too? because it does resemble it A LOT.

Nice progress, the new version already looks a lot better than the first version, but I think if you aa the outline on the outside(outline|background) you should also aa it on the inside(bodyparts|outline).

You really should brighten it up! It's gotten darker with each revision and I can barely see it now. Also, the lightest external aa colors is actually lighter than the background, so it has the opposite effect of smoothing.

There is still some AA missing between his right arm and the outline. I also think that the dark arm should get some light on the right side.

Indeed! And it's been accepted already! Thanks everyone!
