One thing that happens when you spend a lot of time in Sketch Up is that you get so used to the two fingered track pad zoom and "o" orbit shortcut that you start expecting everything to work that way. Even having posted that jpeg export I had an overwhelming urge to zoom in a bit and change the POV.
I also really love the ease of importing images as textures. Painting surfaces with the kind of treatments you have in mind goes a long ways towards getting a feel for how the real thing will work.
BTW, this is all in the free version, 6.4. Do you happen to know if v7, or the "pro" version gives me a little more flexibility with lighting? Shadows and moving the sun around usually just make the stuff I work with look fucked up.
That which doesn't kill you weakens you slightly and makes you less able to cope until you're completely incapacitated
