When I saw this as a thumbnail I was attracted by the blue planet with the strong light fadeing to yellow, guarded by those symmetrical horses.
All in all I like the lighting concept, with the darker foreground where only some hard lights are reflecting.
Also the general reflections and lighting concept es really, really well done. Objects fit fine together and give it a really realistic yet surreal appearance.
The point of most criticism is the chruch's fassade, which somehow doesen't really fit in it's perspective. You tried to fix the proportions of the slightly downlooking angle by makeing the upper parts wider than the under parts, that's great, but from the "inner" walls of the lower arches you can still tell that the original picture was taken from beneath.
I took a long time figuering out what exactly is wrong with that church, though you seemed to have done everything right. Perhaps you also had this phenomenon when working on it.
Another really little thing is, that if you look carefully the men's hood is reflecting really warm light, while the womens face and other skin parts seem very pale and cold.
All in all I think the failure witht he chruch element really somehow ruins the great concept and outcome of the picture in general, cause it gives you the feeling of something that is just not right, though you don't really see technical mistakes on the first sight.
Nethertheless you did a REALLY good job on the rest!
