The Palace UDK

I know you said not to worry about the environment, but the transition between the building and the ground is very abrupt on the far left and right. Some sort of trim on the bottom, basement windows or the like, would probably help it blend. Maybe planters along the base?

I'd break up those flat roofs on either side with dormers or some kind of trim.

i knew it was nymphenburg as soon as i saw it, if that counts as a positive.

on the negative, while the central building looks pretty good, the wings look pretty off, just in terms of general classical proportion (not checking the source for accuracy). the pilasters are relatively heavy, and look like they're floating above the ground floor rather than resting on it (most evident at the corner of that building in the last image). i would think the ground floor would be a different material/color (show modularity through rustication, maybe?) and would be beefed out a little to help solve this. also, the entablature is either too big or too bare, and is contributing to the imbalance in the stuff below. seems like a missed opportunity to show even more modularity through ornament/texture, if you were to decide to keep it on the big side.

good luck with the project.

I found all the windows a bit too flat. You can easily see that most od them are just put on the wall.
