hi all,
here’s my latest test a simple scene with depth of field. What do u guys think?

Nicely lit man! Pretty realistic lighting. The wood looks pretty good too. The marbles do look a bit rough and it looks like the texture was painted, but besides that its sweet. Maybe add a bunch more marbles and rotate them around to bring out the depth of field more. Keep it up
