It looks just about ready - there are 3 areas i dont feel are as of high a quality as the rest of the piece (which i think looks good)
1. the right of his face (our left) - is this an intentional disfigurement? if it is maybe try some colouring it in a way in which it says so, otherwise the outline shape needs an edit (it juts out too harshly from his cheek and should come in slightly by his eye the dark eyebrow line would also need altering)
2. his left arm (our right) - its lacks any feeling of anatomy and to be that length must be bent (coming towards the viewer) the shading needs to reflect that.
3. his belly - im having trouble deciding if this is anatomical and his top half should be shifted left but the shading on his belly is too distracting.
EDIT - i think i lost my vote by posting this before voting!
