Wow thanks I never even thought about that before.

 cool work. very hard.

but something wrong with legs, not smoth enough in lines. 

Awesome. Little bit of "emo" style but is ok. Congrats!

Please do try and edit the legs.. I love this! But it was really the first and only thing stopping me from faving it

Hi ad0xa, you have done a pretty good job on the hair but the outlines of the body is suffering from what is called banding - a jagged, staircase appearance. It's fairly easy to negotiate by just cutting of pixels in opposite directions so colors overlap rather than line-up (as you can see in the right edited image). On the right side of the leg you can see a (anti-banding) dithering technique  good for lines with "small angles" and when interpolating colors are missing.
