Stormsurge with Chain Rail Gun

I'm pretty close to calling it quits on this Stormsurge and moving onto something else. I am working on the base, and I need to paint the ammunition drone and mount it onto the base as well. I finally posted all of my parts to the shapeways marketplace and they are at the bottom of the list.
