Upload & Sell: Off
Thank you all for the tips!!
I tried again on this last night, but I didn't have much luck. I'm getting stuck between "bland" and "way oversaturated." It doesn't help that I accidentally saved over the photoshop file for the above version (like an idiot).
I'm generally going for a colorful-but-not-totally-trippy effect if possible. This is actually a pic that my fiancee composed, and I'm trying to make it into something neat for the wall. The original is very low-contrast. I'm not sure whether I under-exposed it originally or what, but the colorful one is closer to the memory that we both have (we weren't on drugs, I swear!). Here is the straight-out-of-the-camera original:

Rustybug & alatoo60: I agree about the blue on the walls & in the water. I'm going to try to tone that down next time. Thanks.
sbeme: I totally agree that something is off generally. I was going for colorful, but missed...
Auntipode: I agree that the water looks weird. I think it has to do with the slight black border around the river. I'm not sure why, but that is present in the original images too. It may just be splashing on the canyon walls.
cgardner: Thanks. You are right -- the rocks & black void on the bottom right are distracting. I'll tone down the rocks, but I'm not sure what to do about the black void. Even in the originals, that space is very close to being black. I'm pretty sure that it is a stand of trees on the cliff wall, that just happens to be out of the sun.
Thanks for the comments!
