This thead should be under Pimping & Previews. No one is going to see this thread here. :/
Yep, message a mod to get it moved.
Feedback: You're human renders would instantly benefit from having some sort of skin texture on them. You want to use SSS in combination with a diffuse texture. There is a slot there for it. Specularity will make or break it, so you'll want a nice spec map as well. For starters, you can take your diffuse texture and go into Photoshop and put a high pass filter on it. There was just a thread on this in tech talk.
The hair line is too perfect and/or too spaced out. This is probably because you wanted to keep your render times down, understandable. You may want to look into using alpha planes as hair though. They can look just as good.
Brilliant table work. I feel like there is something off with the metal on the table legs though. Perhaps look into increasing your glossy samples.
Your couch is suffering from bad lighting. I would love to see more softness on it too to emulate velvet, or some other soft fabric.
Great start. When did you start learning all of this?
