Back at home and I find a...WARRRRR!!
Not at all, well, Aumio...I'll try to show as simple this can be.
What you do are cvs-ish paletes. They got the brightness and an "overall" lighting similar to CvS, that may look nice in some free sprites BUT in the other hand, looks terrible for entire animations. Look at your Orochi's stand animation:
Mukai, in the other hand, looks nice.Magaki is terrible...not only you chose wrong colours...the shading in his body and clothes are different than expected. That happens in SF2 too, for example. I did a "cvs" palete for Cammy and hey! she looks awesome in some sprites while in others is a total mess.
BUT!! Here's what I think Aumio wanted to share(not sure, correct me if I'm wrong...haven't read the WHOLE thing). You can make those "cvs-ish" paletes, extract the sprites with those colours AND putting an extra colour(like a gradation), and small fixes here and there. Just take a special attention at folds(SNK's are more complex than those of CvS). As example, the stand of Xiangfei of your first page. While the oveall thing is cooly done, the lower knee folds are not right. WHY? They look totally bright while those must be one tone deeper.
Said this, I leave, have a nice day!
I swear there was something cool here!!
