Hi Arash,
I have many similar images of half dome and I will say that I do feel like Ramesh does about them.......I prefer it lit a bit more or even less where just the top rim gets lit. You did well with the exposure and have detail throughout the shadow areas and I even like the way you framed Half Dome, minimizing the sky......maybe a bit of clouds would have helped but you did the best you could under the conditions given.....we can't always have the clouds we want!
Beautiful colors on the rock Arash and the detail is well captured. You might try a selective curves or multiply layer on the sky to see if you can darken it up a bit. Agree with Roman that clouds would have helped but they are seldom around when you need them.
