I’d be happy to help you out with an animation but would need some specific measurements and photo details of the sculpture… maybe you could put them in a dropbox and share that link…but
However, my recommendation to you would be to shoot this on green screen (or similar - maybe even black or white and use a luminance key) so you could pull a matte and overlay it on any other image or video of a client’s building. The reason I would go this route is that you already have this sculpture built and working and would get the full fidelity of its glorious details. From your original post I didn’t know that it existed but that you wanted to visualize an idea.
The reason to do something like this in sketchup would be if the sculpture didn’t exist and you needed to visualize it, then of course it would make more sense. I’m not sure the workload would be much different. Even as a Sketchup animation render, I would output it with an alpha channel and composite it afterwards so that you could overlay it with other, different backgrounds if needed. Ideally, each animation render should be unique as it would need to be lit with, and be seen to reflect the specific background image and light so it blends seamlessly, but as the renders do take hours that may not be as practical.
Anyway, have a think about that and let me know.
