A kitchen chair, is a image for a online shop
Image for an online shop? So, this is a real product then, that you’re replicating digitally? If so, do you have a reference photo with which to compare it that you could post?
I would say that the lighting is a tiny tiny bit too bright, maybe .05 too much. The shadows just look a bit too pronounced. The materials look good though, as does the modeling. Nice job.
Looks good. But a image to compare it to would indeed be nice!
Nice rendering!
