Metal doesn’t look very metalish, it looks like you put texture in the wrong map slot. Also why did you choose isometric projection over perspective?
Anyway, keep working and posting your results!
Thanks for your comment!
I checked the metal; texture is only in bump and anisotropic rotation channel. But I noticed my IOR was too low, at about 15.
Isometric because it made the thing look a little more technical - at least I think that was the reason 
Thanks, I figure only trial and error will improve my work but there is just not enough time next to a full time job…
Going for isometric and dof is not a good combination in my opinion.
Now it looks kinda odd to me too…
It was a pretty spontaneous descision to add dof in post.
Maybe I’ll render another version with perspective projection and dof rendered directly by corona!
