Well it looks like you traced over the image but did little shading and the lines aren't smooth enough.

anti-aliasing. Like using grey to smooth out a place where black and white meet.  And posting a WIP in the WIP thread would help a lot, then post in the gallery when you're pleased with the result.

whats aa mean? O.o i see that on lots of peoples comments for other pixels

Also, some effective AA and replacement of black lines is in order i imagine. There are plently of AAing tutorials out there if you need any, along with dithering. Although if you're new at dithering i don't think it would help this piece. Anime usually uses cell shading, therefore in pixel art with flat shadows and AAing.

On the hair don't be afraid to get detailed in the shading. Think about it, with this style of art, the hair comes out in spikey chunks, so for each chunk there should be shadow on the underside. This should be done throughout all of that orange space of hair. Just think about it as if the hair was a 3D object.

oo alright then, thanks for the help =P well the only reason i wanted to try dithering was cause i dont know how to do it =X

I agree, don't dither. Just give the hair a lightsource, it has shadow all around, making it look "pillowshaded"

I'm not sure you should dither this piece.

I think more shading of the hair and face could greatly enhance this piece.  Please do re-post Rynmaru's rendition of the piece once he's finished. I am learning too. :)

yea sure man, go give it a try and any suggestions on improving it? check out your gallery as well, nice work =P

nice lineart, could i give it a try?

i dont think this piece is very suited for dithering.
