First off, really interesting architecture like a mix of oriental, islandic, and a touch of sci-fi. Secondly, the landscape itself is very appealing to me. The values sit nicely, colors are soft and the vegetation looks just stellar. The only notable thing that bothers me about this scene would be the horn-shaped mountain just above the center structure. Generally the eyes of the viewer would roll down the foot of the large mountain on the left (you even have 3 beautiful statues guiding you) and reach the main building, the most important point of the painting, and then roll on towards the right to finally hit the wall on the right edge, possible doing a backflip and returning to the center building . The horn-shaped mountain, however, runs the risk of yanking the viewer straight upwards, interupting an otherwise pleasant journey. Of course this is just my experience, and I would not consider myself an expert on composition as I've had my fair share of hiccups as well.
All in all, I would consider this a very strong piece, really something to be proud of Two thumbs up!
