As I mentioned in another thread recently, the problem with Yosemite in general is that it is a drab, grey featureless place. When you look at some of the "classic" photographs taken there - such as Adams's "Clearing Winter Storm", taken from a similar viewpoint to yours - the drama in the image comes almost entirely from the weather and clouds. If you do a Google Images search for Yosemite Tunnel View or, indeed, just Yosemite, you will find 99 drab images for every one spectacular one.
Catch the valley in the right conditions and you can get a great photograph. But, 19 days out of 20...........
