Critique my WIP interior shots

[jet1990]

Hi all new to this forum, Im currently trying to perfect interior rendering shots as im branching out my skill set into my business. Let me know what you think. For me, lighting has always being the make or break so im trying my hardest to get the best possible shots that could rival programs such as Vray but i often find there's quite a bit of noise in my renders unless i really boost up the sample rate of materials.

One light source is probably not enough to get representing image. Don't be afraid to light up the room from inside to give more light bounce and dynamics.
