Commissions frenzy continues, this is only 2nd one

This drawing is on A4 format paper, drawn using only graphite ranging from 3H to 8B, plus white gel pen.
I also used regular eraser, pencil eraser and kneaded eraser and for blending I used earscoop and Kleenex.

Please comment, I would love to hear your oppinion to improve my technique
Enjoy!
