Cool looking scenes, like the carpet/rug, I think its awsome but as pointed out, the specularity is too much, sort of thing that needs a bright light to produce or an extremely wet surface.

Something I havnt seen yet (probably just my bad...) is a varnished wood effect which maybe the spec could really help define with a bit of ambient spread to give it a richness for the eyes (dont know as shader work is too advanced for me )

Nice project!
