Very nice, Michael. I might suggest that while blending H-a and S-II for red, and using O-III for blue/green gives you somewhat realistic (natural) color, you can get more variation in the hue by using a more "mixed up" blend. I don't remember exactly what mix I used, but it probably included blending some S-II into the green channel: http://storage.ning.com/topology/rest/1.0/file/get/2762655719?profi...
