I really like them Poon.
Definately agree with Nnnsic about number 1.
My pick for pose would be number 3 but the face seems a little soft. Could just be my eyes though.
I don't have the expertise to give you any advice though. One thing I can say is that you must have established a good connection with the
model as she seems very relaxed and comfortable in the poses. Great background setting aswell.
Great work!
