Nice hair. :) The detail in the character is great, especially the last picture, nice mixture of shadow and brushes. Also nice how the colors flow together. As for the background, the mountain seems too rigid in comparisson to the detailed greenery beside it, it's like a clash of styles. Might want to add some borders to the character squares as well, it seems they don't seperate from the background enough. Otherwise it looks great! Hope you post of the rest of this here at NG! :)
