Sculpting work on Obliterator

I have set aside one of the 5 Chaos Terminators to convert him into an Obliterator.  I finally got around to doing the green stuff today.  I am going to let it sit overnight to make sure it has completely cured, but I am excited to see what it looks like once it is ready to paint.

I am also going to test out some paint schemes on some of the regular Space Marines to see what I want to do for my Plague Marines.  I am thinking of doing something different from the normal green everything and have some other colors going on.  Before committing that to the Plague Marines I want to try it out.
