Sorry for double post.
Quick update on things, not adding Blaziken yet since he didn't look right...
Basic colours, no shading yet. Bellsprout looks a bit weak though :/
And for Ditto, eyes and smile combo for A, B, or C?
C+C please
Colors = Looks good, particularly Zangoose's markings.
Bellsprout = Looks odd because of the mouth and odd shaped leaves. Mouth looks too thick for a ring(Although this would be hard for anyone), and the leaves just look odd.
Ditto = B, by far. Decision on the blob arms?
Well I orignally planned of having him just extend them from his body, which is why his shape has been what it is, and without the showable arms.
I guessed that you might have done that. It's a good idea.
Trial of shading, doing Nuzleaf, he'd be the easiest to shade currently. Shading's my worst part though... C+C?
There are several issues with the head alone, so if you don't mind I'll help you with this edit:
I fixed the nose, removed the mask's outline, and gave him a bigger leaf
Is this any better at all?
Well, you can't see the bottom outline of the nose, and it blends in with the mask. I'd suggest fixing that and maybe some hue shifting
Like this Norsk? And by hue shifting you're referring to the shading, correct?
yes and yes
though i think hue shifting is needed on the mask mostly
Oh so like this
thats barely a hue shift, sir
Well I used the shade from the DPP sprite, since the mask's base colour is literally the same.
