thank you very much!!!!!!
for the first point,i will pay more attention about it ,but most time i would like to draw a circle to keep proportion.
second,i drawed that contour after each practice because i think it is easy to be recognized what the pose be.i draw that hand which is not necessary far to make image more completely (may be just i think).
third ,actually, each image is not small as you think. they have 13-16cm height at least!!
thank you for you time
