Yeah, how about less in the skin? The clothes are okay but the skin just looks... wierd with that much dithering.

But if you say the colors look rough, how about try a different dithering pattern/approach?

 The dithering in my opinion is fine, besides the skin.  I think it helps create texture for the clothes, but the skin is supposed to be shiny and smooth so it shouldn't have that excessive dithering

 Thanks for your comments :) : that's important for me to keep motivated and keep time to improve my technics.

Dithering is done here in order to add some effects such as whool like on the shirt. The skirt is then more synthetic, could have less dithering maybe, you're proobably right.
Tried to do a leather boots texture.

About arms and leg,   I tried without dithering, but it seems / looks to me as if it was too rough, simple, not enough smooth. So you think i should have keep it simplier ?

thats some heavy over dithering

I agree with uhmmm in that the dithering distracts from the overall piece. It looks better than your previous sprite in this style, though.

i agree she looks cute, it looks like really pixelated, nice pix ^^

Yeah, she looks cute. But, the dithering looks a little too intense. Maybe use less next time?
