1) The ninja kind of looks like he's resting his head on the back of his head in 35, can you make it do something else (out behind him, down, pointing forward, holding a sword straight horizontally).
2) Can you try some different background colors for the icon? The pinkish color is cool but maybe try some retro blues/greens instead.
3) Different colors to try for the font. I like the mix of colors, just please try some different colors and we'll see how it looks.
