Yes I'm aware of the wood being to perfect. I actually did paint on it but its not noticeable in Marmoset. Never done this setup before so i've must have missed something :P
I've been involved with a lot of architecture visualization work lately, so your perfect wood doesn't come off all that bad to me honestly. I think your DoF is sexy, the copper looks nice, the wood doesn't have to many details to distract from the rest of it, and it's over all simple yet well done. For pure skill application sure you can go ahead and do the dust/imperfections, definitely wouldn't hurt the piece, but I think it looks good right now if you asked me
What settings are you using for your scene in MT2?
