Hi @namdao, great job! "And my english is not very good" I'll try to express myself simply. Feel free to ask if there is anything you don't understand :) PROPORTION -The eye's are too big, compared to the photo SEPARATE LIGHTS AND DARKS The whole side of the head should be in shadow. If you squint at the photo, can you see how all the dark parts, become darker and blend together? Squinting is a good way to figure out whether something belongs to light or shadow. I hope this was helpful :)
