A lot of weeaboos(Another word for a person thats obsessed over anime) call it chibi, another word for 'super-deformed', its an art style, a bit related to anime.

25 colors, good god, thats alot especially for a small piece such as this, thats too much, there's just alot of other problems with the overall person, especially face structure. Okay, so I googled some chibis and here's the best I got:

Now the main thing you're seeing here is that the face is the largest feature on the person, hands and feet are also pretty large. With the eyes and other things, they just don't look like anime eyes, the pupil on the eye is basically covering over 90% of the body, where it's chibi or not, so what I think you should do is look at some examples of eyes, face structures, etc. from here:

Other crits: Human skin isn't that shiny, the light source isn't really defined too well, a bit pillow-shadish in places, the way he's facing is weird, his face is looking right, along with his body, then the legs are facing left, not only that but his shoulders are uneven and its hard to tell where his hands are.

 Thanks for the advice. I didn't really intend him to be an anime chibi. This was more of an original design. I'll work on the skin.

Thanks! I really like edit. I'll take it and learn from it. I like the effects you added, it fits this type of character.

 I was pixeling him for a site. He's the protagonist from the game series Crusader by Origins.

Bruce Lee's one of my favorite legends also. Try adding some brown or some reddish brown to his hair. Asians actually look cool with hair colored than natural black. Check out Fei Long and Ryu from Street Fighter for that inspiration.
