Experimenting with the render code parameters

I started playing with the render code parameters to see if I could get a reasonable render out that was similar to maya.  The main alteration was in the exposure setting.  It was at 0.005 initially.  I changed it to 0.1, and now the opaque layer of particles seems closer to what I expected.  Here's some progress stills.

Initial Render: exposure = 0.005

exposure = 1.0

exposure = 0.5

exposure = 0.1

Alpha: the edges are brighter b/c of the curved edge build up
