Since you asked, Knid, I really love the pen-and-ink look. Sometimes, though, it makes some detail harder to see. The color images are attractive too. I guess the sepia is my least favorite, because it looks machine done, whereas the other versions don't look that way as much.
Your work is really good, Knid.
Now, since you said you wanted more ideas, how about this: I was thinking about an enclosed garden that was part of a palace complex. Maybe a place the monarch had set aside for the fey folk with whom he has entered into some sort of mutual protection agreement. It would be walled all around, with no entry or exit except through the palace, unless you can fly. It would have lots of beautiful flowers, maybe some trees and shrubery with fey houses built into or around them. It would need to look magical somehow. I'm not sure how you would do that.
