It's really hard to make out what's going on here; only the stars and moon are clearly visible at 1x or even 2x. I also don't like the dithering. Focus on shapes before detail. Nice moon, though.
I had to blow it up before I could see what it was. The cloud between the moon and the wolf obscures the shape of the wolf and makes it hard to read. I think it'd look pretty good if those clouds were lightened up (just now noticed the bottom right one). Right now everything but the moon and stars are just too similar color
I really like this piece although I do agree that the cloud above the wolf is a little obscuring it is really well done :D
