This is one of my latest renders. I made the pool table and everything else you see in Maya, and Rendered with Maxwell Render. Nothing in this Image in real.
It's a well done computer generation. The cloth surface doesn't appear smooth enough, and there are a few ways of smoothing, but a good Noise Reduction utility does a very nice job without affecting the sharpness elsewhere.
Very realistic! There's something about the window frame that doesn't seem quite right (it leans inwards? Maybe it's meant to, but it doesn't seem to square up with the set of pool cues). Apart from that, I like the way you can see structures through the glass.
Wow! I am awestruck and this meticulous digital image. If you hadn't told us, I would have thought it was real. I especially like the detail work on the tiles and, of course, the subject is great. Well done.
