Classic shader problem in a 3D rendering app - when the flat surface meets a curved edge you get a crease along the line. This is because most shadow calculations are done on a per-face basis.

In real life, getting such a fine crease is really difficult. In a 3D render? All but certain.

Also, the flawless wooden table.

Looks photoshopped to me. Unless its a weird lighting effect on the metal, the shadows between the two devices don't look right.

Everything about it looks like a render, the desk texture, the lighting of the white leads. Looks nice though.
