Ok so after I posted this I figured I'd experiment a bit - love like goofing around in photoshop - so I did up these. Stream is tilted a few degrees to the right, I've burned in the trees a bit to try and get rid of the hot area in the middle (mixed results there, it's still hot) and I did a little slide effect on the water to try and make it look more fluid. Remember, I did this quickly so it's not perfect but you get the idea.
Also took the moon shot and tried to darken the sky a bit and clone out the birds which distracted me. the more I played with it the more I prefer stream as it has more life to it. Again, this was done quickly and not sure if it's different than what you've done...now looking at yours
