Hi Loi - I really like the comp here and the dof. Nice detail too. The elephants seem a little light so I might just selectively give them a boost either in curves or by adding a couple of points to black and neutrals in selective color.
Thank you all for your feedback. Brightness is quite difficult for me to judge even though I've calibrated my monitor. The image posted here on the BPN site looks a bit brighter than the same image i have in JPG. I added a little more contrast using Curves and cloned out a small dark spot on the LHS. Let's see how it compares with the OP. Loi
Thank you everyone for your comments. Here is a repost with the elephants darkened by using Curves. Thank you Rachel for suggestion. Hope you like it better.
