Thanks, Heddheld.  I'm really disappointed I didn't get more feedback on the image.  Even if it wasn't all positive, I expected to see some more comments, considering how many Blender users there are on this website.  Oh well.  I'm really proud of the image.  I was never one for coming up with great materials, especially in Cycles.  I found it difficult to even follow some tutorials for materials actually.  The node structure there was all mine.  Yes, I was definitely going after a plastic, artificial look for the pine needles, so I'm glad you noticed that!  The background is a HDRI of a room.  It's not supposed to be "empty", which is why I used a HDR environment, to give it the illusion of a real environment, but the ornaments are intentionally hanging by themselves.  I'm just not very good at scene construction yet.  I can model, but materials and composition are still my weakness.  While I didn't model the main object in that scene, I did model the other ornaments, and like I said, the materials and lighting are all me.

Thanks for giving me some feedback!  I really need it.
