3d interior Type Phase 1

Nice rendering...though there are a couple of problems... The most exposed inefficiency is observable at nearly all of the corners; the blotches caused by light leaking. That could be rectified by increasing the IrradianceMap HSph.subdivs amount. Additionally, I reckon that the displacement map (a default noise procedural map?) would not be suitable enough for the carpet. It's in an extremely large scale...Maybe you had better utilize a map derived from the diffuse map, in Photoshop.
