I hope you don't mind me offering my opinion?
The first work you posted is just great. I really could see me living with that on a wall in our house. The second is still good, but not, in my opinion, as good as the first, although I still really like it. The third, I'm sorry, I personally could take or leave.
I'm about as far from an artist myself as it's possible to get (I struggle to draw the curtains!), so I hope you'll take these comments in the spirit they're intended. I really wish I could put my finger on what it is about the works that makes me feel what I do, but I'm not sure. Maybe I like the other worldly atmosphere that somebody else mentioned?
Anyway, please keep posting - I'm always in awe of people who have talents in areas I don't.
