Great color and concept. Love the ominous clouds, but..... The mountain tops appear to be cut and pasted in. I don't know maybe to contrasty?? Nice job other than that!
If I didn't check the category I could say it was a photograph... Really made a big impression on me. Surprising, but I never find such amazing computer landscapes in the voting booth. And you would surely score very high...
I like the 'potential power' that is evident in your image here. It appears that something has been released and is changing the skyscape ... maybe more.
At least that is my humble interpretation.
But, powerful is the operative word for your visual here.
