What do you guys think, any critiques?

The penny material is the most complicated, if you want to see the node setup, just ask.

There is an animation of this scene in the works also, I’ll post it in the comments, and in a new thread.

AO pass,

and the full scene.

I like it, what is the setting? The lighting looks like an attic. One minor critic I’d add a bit of gloss to the edges to show some wear.
