Oh, yes it looks nice and the marble isn't too close. The plant does look overall just a little bit pale to me though. Maybe the color is washed out a bit in the picture?
Also there are a few leaves near the bottom of the photo with a reddish tinge - could be some fert with a little extra Epsom salts would help green it up a bit. Still, I'd go light on the fert until you're sure the plant isn't in distress. A watering can of soluble plant food at half strength, with a tablespoon or two of Epsom salts, and wait a week or two to see the results. If the color improves, I'd put down some time-release pelleted fert that will last the rest of the summer and leave it be.
