small portrait help

[Shutterbug]

Hi all

Hoping somebody with clever skills can help me fix the palette problem with this custom character, Lee, a remake from "street fighter" 1.
Here is the UNMODIFIED file, for reference

and here is the modified file with my custom small and big portrait

Can anybody help me? I'd appreciate it
