Israf'l is pretty much a straight forward Terminator Librarian, right out of the package. I don't think I added more than a couple small pieces of DA paraphernalia to him. Mik'l is pretty heavily modified from a White Dwarf release terminator, with the Dark Angels terminator power sword and other paraphernalia attached. The white thing on his right shoulder is the edge of a robed angel's wing. I'll get a profile shot later.
These are the shots that came out well from the ones I worked on this evening... sadly they're both color patterns - neither one represents the coloration of the army as a whole. Hopefully will get some more of those soon.
