Zeena Palettes

Hey everyone!
I wanted to try something different for a change, so I've decided to make pixel art in Photoshop. Since I'm intrigued in these new 'bosses' or 'monsters' or 'creatures' from Sonic Lost World, I wasn't sure which one to choose. It's not until I kept seeing 'Game Boy' related deviations that I've finally decided to do a sprite of the one and only female boss in the game... Zeena. The reason why I chose her is because... well... the color palette of the Game Boy. I wanted to see how it was like to be limited to certain colors.

First one of the left is of course, the most detailed I could come up with, with lights and shades.
Second, Nintendo Entertainment color palette. There is no such thing as dark grey in this palette.
Third, Sega Master System with its lack of variety for the color green compared to the NES.
Fourth and Fifth, Two different types of Game Boy color palettes, with a limitation of 4 colors.
Sixth, well... why the heck not? XD

Comments would be appreciated... just let me know what you think. OK bye.
