Wicked! I love the design of the castle, and the location of it makes it even more beautiful. The perspective might be a little off, I think the two men and the horse are too big here unless the castle isn't as big as one could imagine... but overall, it's a nice job here.
This looks cool and the lighting is really nice, even the snowpack behind the castle despite how rough it is. :0 But I'm not really getting a sense of scale from it. It looks like horse rider's flag would knock about the top of the top of the door frame, but from looking at the castle alone, it looks like it should be a lot bigger than that. I think adding a figure by the door would help a lot.
