Hi Buttie, its been a long time since we last met. hope u are fine.
#2 and #6 gets my vote.
Noob comments:
Whats good: #2, USed the surrounding light well.
#6, You have found the right time to snap this shot, and u have a great model
Suggestions: #2, I would have include the top right painting in as well, and exclude the glass table.
#6, I would have go lower slightly and frame in the Coconut tree above his head, and ask him look abit more to his left.
Above comments are my noob comments, i may be wrong, cos i am not a pro or what. Its just to share.
Cheers..
