High poly kitchen on a sunny day with some textures. Cycles
Maybe he is a fan of his own kitchen or he has some company brands show up somewhere.
I think the shadows are fairly realistic, if the room has a good window and the sun is shining. I've certainly seen shadows like these. If anything, I think it's missing a bit of glare.
Try plugging the words "kitchen sunlight" (without quotes) into Google Image search to see what I mean.
This is awezome but NOT fan art
