I'm glad you're making a print out of this, because it's really going to look fantastic matted and framed. The colors are really outstanding, and the shadow is really intriguing. The contrast is subtle, but I like it like that. It really makes you wonder what the building looked like, and shows they constructed the building out of what they had readily available.
Compositionally I like this man. At first when you look at it it doesn't appear to have much depth, but when when you view it larger you can see to the left of the ruins how vast the location really is. If you stepped back a bit you probably could have gotten a little more in front of the ruins, but that's really just nitpicking.
Processing wise, you remained subtle and not overwhelming, and I like that a lot. Your stitch of the two photos was also flawless, definitely no issues there.
thank you, after i took this the structure became bright orange almost as bright as the sun, i would have taken a photo of it but would have had to take some of the colors out anyways...it was an amazing place
