very nicely done.
I would try lowering the brightness in the top left side of the mountains- seems a little washed out and also in the top right just to the right of the mountain peak. See if this balances the exposure and makes the image stronger. My 2c
I got lucky with an early morning and perfectly calm air which gave me my greatest distance view that I've had over Death Valley. I did a 6 shot vertical pano with my 100mm macro and stitched them in PS.
I really like this shot. It looks natural and very pleasing overall. It puts me right there in that wonderful place. Like I have said before not all great views translate into great photographs but thats not the case here!
Very nice, it's really amazing how far the panorama stitching software has come. It is to the point now where high quality stitched panos are commonplace and some amazing resolution is at everyone's fingertips.
