Very nice, the colours and Bg are great, it looks sharp and EXP looks good to, I only wish for a bit better profile view and less room behind him. Conmgratulations, the flowers adds a lot to the whole scene!
First off, there is bad posterization in the BG. Perhaps your resizing for web method has contributed to this. I agree with Ramone, but I feel like I want to see more of the plant (the greenery is cut short).
There is no flash just natural light as far as the jpeg artifacts i took a 11x14 and made it to that size i guess that is were things went wrong . thanks for the comments
