Snake(?) next to warrior on top of gate mmh, doesn't feel right. Doesn't even feel like it could possibly be coiled like this on top of the gate. Although I like the glittery path I think there are interesting details on right of pic that could gain by contrasting a little more maybe?
Overall pretty good, just trying to bring some constructive comments.
I want to critique something about that cloud in the back, but I can't figure out what...
It looks great: scale, direction, lighting, focus. I don't paint nearly as good of course, but I would probably paint some highlights on the outline of those rocks (the rock on the left specfiicaly) - just something I feel like doing if it was given to me to mess with.
