The colors are absolutely breathtaking! You've captured its beauty and charm so well, as well as getting a phenomenal shot! The colors stand out so well, and the balance and harmony of the piece is great.
I also ADORE how you managed to capture one of the Jammer Busses going by in there as well, since they are a bit of a symbol of the park (at least, they are to us locals haha they symbolize tourist season lol).
Personally, I think the moon should be just a tad smaller and a bit more faded, to make it blend in better, but it still looks great. Kudos on such an awesome shot!!
it would be better to put in a quarter moon, at the minimum, in this image. that would integrate better with the lighting. also, this image obviously was not taken with a telephoto lens, so the moon should be smaller than shown here, but this point is not as important as what i said above.
it's a nice idea to put a moon in this image, but it's not at the right place and angle, according to what the rest of the image shows. the moon says that the sun is just at the horizon line on the left side of the image, but the sunlight on the mountains says otherwise.
