the problem we have here, is that you don't have much contrast between your gray shades. Contrast is difference between each color you are using. In this case, the guy's armor isn't well-defined as Naruto's color and details are. Comparing to Samus, though, it's somewhat similar.

One thing that remains true between Naruto and Samus, though, is the saturation of the colors. If you see their colors, you'll see that they appear more bright, lively and cartoonish. Your sprite looks gritty because of that, and looks out of place considering the style you're trying to emulate.

Finally, his feet are misplaced. Both Samus and Naruto have their feet in the same level, now your sprite has one foot placed further than the other.
