Comping Stuff Together

Here are the comped layers.  I tried clamping the edge alpha more to see if I could get rid of the icky black edges... its a little better now at alpha^5 and alpha^6.

3 Layers: Low opaque, low transparent, top opaque

alpha^4 edges

alpha^5 edges

alpha^6 edges

All 4 Layers: low opaque, low transparent, top opaque, top transparent

alpha^4

alpha^6
