"The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts." Bertrand Russell
Nice work. Good composition and nice color. The outline of the mountains is a bit harsh against the sky, maybe you could have more mountains in the distance to soften it a bit. Also there is some pixelation in the sky, especially around the moon, which could probably be fixed by some light blurring. But overall I like it.
