Mostly about the lighting - modelling is fairly simple, as are most of the textures/materials
Looks nice, maybe add a sun lamp to cast off stronger shadows. Also some green color is too strong, maybe you should lighten it a bit.
Overall, lovely work
Not bad I agree that you should add a sun lamp as it will look a bit nicer, and help cast more realistic shadows. Also, some of the modelling seems very basic…the table for example doesn’t seem to have any detail (join marks etc…) Overall tho, not bad
