Why the last one? You sound almost apologetic... no need to be, I assure you. All the images of your Tibet trip which you have posted are in the range pretty good to outstanding, including this one. Please post some more.
I agree with Russ about the oversharpening though, both for this and most of the others; you might want to tone it down a bit in this regard.
I totally agree with Ed and Russ. Do show us some more, please.
