really good collection.
some mistakes here and there, like not many details for Yoshimitsu's clothes (but I guess it would be hell to render in pixel-art), maybe Brian should be the same size of kazuya and other shape/antialiasing improvements can be done... but overall really nice gallery
is the word "frankenspriting" still in use in the mugen world nowadays?
also good luck on your project, if you're going to make a full game out of it... a hell of a work awaits you ;*))
