Nice 3-D

So here was something "NICE" the 3-D skills are really good and this looked like the real thing here, I might suggest some added backround detail, Edges appear "FIRM" and unyielding, while the surfaces "HOLD-TRUE" to actual wooden desktops, The computer and speakers on the desktop are especially detailed as is "THE-PATERN" along the wood making it a remarkable piece of digital artwork.

Good lighting

Actually, I was going to say the lighting is one of the strengths of this render, as far as making the model look good. The wood looks great, the other stuff not as much. But overall it has a nice solidity to it.

Sine you were going for realistic...

I can't give you too many points after you've stated your intention. However, the model itself is quite nice. There isn't a whole lot of detail in this, but there doesn't need to be. You did what there was to be done correctly.

This is lacking the proper materials and lighting, but I'm sure you know that because your robots are more than ten times better.
