gotta love yellowstone. Good corrections in PS - realistic colors, good depth to the pool, and nice even tones.
Most of the thermal features are difficult to shoot through withoug a wider lens, glad that you got a nice shot.
Recommendation would be to use a little bit of the rule of thirds or a wide angle to compose the surroundings. This cannot be done without another lens sometimes, and I understand.
I've got a yellowstone portfolio, and maybe you can see what I mean...
Hope you enjoyed the location - Yellowstone is great.
