As for Voltorb and Electrode, you're on the right path with the first set, but the second set is lacking shading, which you really shouldn't leave out. I still feel like you'd be better off if you actually picked a different set of Pokéballs though, because these just look really plain and not all that original to me.
Golduck is good, but i'd leave the hat off-- Other than that it's nice looking! I think you should be able to move on to the backsprites for this one (Please make sure to have a version with a transparent background though, it'll save time for Jan)
Doduo's colors are still too saturdated and are painful to look at, as well as the shading being barely visible and the colors being generally too dark to distinguish from each other, so I'll have to reject this one again.
Heyyyyy this one is pretty cool! I'm gonna wait with approving this one though because of Hycrox having originally claimed this one, so I'll let Jan make a final judgement on this one later.
Bruhhh these are super nice. Well done! I'll make sure to update the claim list later.
Nice job! All there's left to do is indeed the size fix, and getting rid of that one pixel in the top right corner of the front sprite, and then you should be set.
Looks better than the previous one, but there's the shading issue again; you're using a color that's only slightly darker than the lighter ones, and this makes it look like as if there's no shading.
The Rhydon is also lacking shading as well as having improper use of black, and as much as I like memes and think it's pretty funny what you did, I really don't think I should accept this one.
Looks better than your first attempt, but the colors of the center of the cloyster are still too light. Try using a darker outline, or at least use it for the outline of the mouth and the eyes, as they're barely distinguishable from the rest of the sprite.
There's an anti-aliasing problem here, and the edges are blurry. Also, the colors are a bit too similar to the original sprites, so perhaps try something else?
(Also is that a The Flash reference on the slowbro or what)
