Seems like a decent start. It's very dark though. It might show off your materials better if it was a touch brighter. I didn't even notice the marble until I read your caption. Thanks for sharing.

It looked okay on my main monitor but I tried it now on my second monitor and the difference was crazy, I could barely see anything.
I'll try to play with the lighting a bit more!
