1st renderings--comments please.

I need all the help I can get. Here are my very 1st efforts at rendering.

Lemme have it!

My rendering experience comes from other packages (I'm still learning Revit), so I'll comment your images in a generic way. How to enhance them with Revit is still beyond my experience.

I find the background mountains (and the sky in the image labeled #2) too saturated. However, some people ask for highly saturated and contrasted (illustration-like) images, so I don't know if this is your case for this project.

I liked the one labeled #1 a lot, perhaps because its shadows are more complex than in #2 (they intersect the windows, while in #2 they don't). In #2 I'd try to make the shadows intersect the round columns in the right, as well as some windows if possible.

Also, the lower faces of the roofs are too dark. This is a common problem in raytracing, because the diffuse interreflection (from the floor and walls) is not taken into account. Revit has a radiosity solver, but it seems to be designed for interiors only. There're some raytracers like POV-Ray or Radiance which are able to compute diffuse interreflection no matter if it's an interior or exterior view.

The shaded walls are also a bit "flat" (in both images, although it's more noticeable in #1). This is also caused because of lack of diffuse interreflection. If Revit can't compute diffuse interreflection for exteriors, you can somewhat emulate the effect creating fake lights of low intensity in the places where you want a diffuse bounce.

Hope this helps.
