This is fabulous. I absolutely adore the storybook quality it has. My only real concern is that perhaps you went a little too crazy with the contrast in the foreground? It seems a tad drastic, especially on the left side, where the dark colours make it seem quite heavily-weighted towards the left, almost enough to compete with the citadel which should be the clear focus of the image. It’s possible, however, that simply cropping some of the left side off would address this, but it’s obviously entirely your choice to leave it this way too.
Really cool stuff. It looks like something you’d see at the beginning of a fairy tale film, and I like the way the birds are the only sign of life. Plugged.
