I am rendering now, but I'm wondering if I've gone too far in render time.

Are you looking for fast render times? Because you have the glass and the liquid, the raytrace bounces are a minimum of 4, and you really need 6 to get all the nooks and crannies in the geometry. This is a long render. On my machine it is around 5 to 10 minutes for a medium size rendering where the bottle is the main subject.

If it's just going to be filler content and show up as a small object, it is probably not so long.

For a background object, maybe I'd go with transparency instead of refraction.

I don't know - when I post the render you can judge yourself if it is worth it.

I can promise you this, though - nobody will have a better looking perfume prop than you.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
