I like the pixeling style here, but like Long says it could be more controlled (while keeping the not-so-controlled looks). You might vary the line thickness in places. Textures need more attention. Check that banding.
But the main issue is that the face looks 100% male. You can be sketchy almost everywhere but not there.
I like the piece, but imo this would greatly benefit from cleaning up on the pixel level and/or the excessive use of 0°,90°,and45° lines, also the bag seems to be floating in the air rather than going under the scarf and how about moving the right shoulder/arm a tad higher and the head a tad to the left?
Cool. My sister pointed out the face yesterday. I'll work more on this. It was more of a continuous line and value exercise. Cheers!
