I may's well mention I'm an old Yosemite hand. Many years ago I actually taught workshops there. It's one of my favorite places on earth. And I know how stunningly difficult it can be to take great images there. The lighting issues are very complex because the valley is so deep and narrow, and it twists.
Speaking of your shots collectively, the first thing I notice is that you nearly always are shooting with the light from behind you; over one shoulder, if not directly behind. This, in general, is exactly what you don't want to do in landscape photography, and especially in places like Yosemite, where the texture of the rock is one of its most overpowering features. If you look at Ansel's best shots there, they are so much about texture and luminosity, essentially about the light itself.
I realize that if one is just passing through Yosemite, and especially if one has companions in tow who are not photographically inclined, then one's opportunities are very limited and one must of course make do with what one is provided...
Anyway, this shot, the classic view, the Gateway to Yosemite, aside from suffering from the aforementioned flat light, is oddly tuncated in its framing. One would, especially, epect to see all of El Capitan on the left. And more of the dome to the right would be a plus, as it makes a very nice shape indeed as it curves down there. I don't know if this is as wide as you could go (you didn't list the lens), but wider would be better. Another thing: this classic viewpoint works especially well if one includes more sky; the interplay between the immense sky and the narrow valley, when it's properly lit, is astounding.
It's a great shot. If I look for areas that could be addressed, it does seem to be a bit on the blue side in the center, but it might be just a haze effect.
Its like look at all these huge mountains, the snow covered peeks, and the fantastic colors. Oh, and by the way, did you see the magnificant waterefall?
Nice. Personally, I don't care too much for the crop, just on the top part. I'd like to see the top of El Capitan instead of the cliff rising up through the top of the photo. But I do like having the two trees on the left there kind of framed by the rock face.
