I recently finished a project to do the whole box of Space Hulk minis. These guys are the most dynamic terminators and Genestealers to come out of any Games Workshop line, and they're really quite marvelous to paint.
I painted the lightning arcs onto the power sword and thunder hammer by request of my client. I think both of them turned out rather well.
Overall this project matches the studio scheme for Space Hulk a little more closely than the previous set of terminators that I painted.
