With my somewhat limited knowledge, the best I can remember is that along with the costume, the contenance of the objectified leader is on par with the garb. That alone is a negative hit on this photo. However, the leading lines of the pasageway does help circumvent that issue for me, along with the brilliant capture of the colors of the costume and display of the offerings. You've also captured the etchings on the walls quite nicely to add to the story. I won't comment on the placement of the watermark.
nice composition. I was here last August (2010) and shot a few thousand frames. Amazing place isn't it? I could have spent a week just looking at a single wall with the artwork that adorns every square inch.
Did you climb the stairs to the top of the inner temple and see the pools? Did you go to the other temples nearby?
