Hi Andy,
First off, beautiful colors - Very nice feel and I agree with Oshyan about the trees... Its like a mid afternoon dream

And the render is of very high quality.
But I have to say, in my opinion the composition fails your obvious technical abilities and talent. That is, the image is very symmetrical from the placement of the primary subject in the center of the composition to the terrain's highest visible peak pointing to close to the center of the top portion of the image (rules of thirds).
On the other hand the architecture is based on the Eastern Orthodox line of thinking as in the Hagia Sophia in Constantinople

So symmetry is very important... But since none of that is your point, why limit the composition?
I realize its a 'WIP' and you probably are saving last for last... but I really enjoy these critiques, they are the one thing I miss about school

, well, that and coeds

Also,

...At the moment I'm concentrating on the terrain elevation so the terrain "snuggly fits" the building. (Read that expression long ago in an instruction manual for a Stax tone arm; never forgot it) The way I do it is pretty straight forward but time consuming: I use several Painted shaders, each connected to a Displacement shader. With a separate camera I circle the building and paint the terrain underneath it. With the values for the displacement I can raise or lower the terrain where needed. It's a rather crude method IMO but I do rely on vegetation to mask any imperfections.
Why not just move parts of the model below the terrain by a few inches to a few feet? Or am I missing the point?
Lastly, the statues of the two figures in the center far left of the image should be taken out, I think. They are not working.
Hope I'm not being to forward with my thoughts. Feel free to tell me to back off if I am.
Great work so far, very inspirational!
