I’d like to know how to get it noise free. I rendered it with 700 samples. I only have one light source aside from the HDR. It’s a sun lamp, whose only purpose is to produce sharp shadows.
Looks very nice for a first. I think the wood floor needs a lot of work, it looks flat, stretched, and repetitive. Try scaling your UVs for the floor down. Nice job on the TV though.
Did you watch The Fundamentals series yet? One of the main issues to this image is that there is no point, no subject. So it is a little boring.
As for getting your image to be noise-free, try this:
Turn up your samples
Turn on clamp
Turn on multiple importance sampling
Turn on “No Caustics”.
Try that and you will get a more noise-free image.
