IrfanView says this has 32 or so colours. Your description for this on DA says:"THIS PIXELIS 100% MINE!I don't care what bull song and dance any one gives you. If you see some one claiming it come to me so I can report them half oekaki half photoshop"
In most pixeling circles Oekaki is NPA . HERE's what the colours are (Minus the blue) Why on earth would you use completely different colours for sprite and Backview?
EDIT: All your work's like this :/ Cel-shaded style with heaps of ultrasimilar colours.
