Not judging the overall design, which would make me mentally ill if I would stay there for more that 1 hour, and the mix of green grass and red glass, so let’s get to technical stuff - things that bother me most:
-noise - render settings or materials optimization would be required, or simply longer render time
-metal/reflective materials - they simply don’t look real - they are too uniform, glossy, and plastic-like
-even if most of the materials are purely black&white, I think there should be some little tint of warm/cool hue introduced, maybe even simply by changing color temperature in vfb, such monochromatic look is not realistic
my gosh… everything is wrong on so any levels of design. Yes everyone has different taste, but even rotten eggs and roaches can be eaten by those who have a stomach for it.
looks more like an obstacle in a space… honestly, the interior design can be a lot better even if limited to using only two colours. take note of the points made by Nekrobul and maru is all am asking and also take a look at the numerous posts of interior designs in this forum that have been criticized constructively and you will see you still have work to do.
