Spices And Glasses

-Spices And Glasses-
(Made with Blender 2.69, rendered with Cycles in 2000 samples. Render took about 2 and a half hours.)

Hello. This is my first post in the forum. I have been using Blender a year now and this is one of my first own-made projects. So, what do you think?

I had some questions when making it:

  1. Can you make an emitter emit rigid objects?
  2. Some of the peppers, when falling on the white surface, didn’t completely touch it. Instead, they were “floating” above it, but I couldn’t figure out why. I changed the Ridig Body Shape to Mesh, but it didn’t change.
  3. What is the right way to create lamps (as real objects)? For this scene, I made 4 spheres and gave them the emitter shader. Is there anything else I should do?

P.S.: I know that the purple vase is somewhat floating, but I noticed that during the render and because it took too long to complete, I didn’t render it again.

Try moving the individual peppers after converting them to mesh?
