I just finished up my Raptors version of Shrike. Just the plain Shrike model painted in my Raptors scheme. I didn't really lavish attention on him as the whole raptors 'washes' paint scheme is more speed over quality. This model also wasn't the best cast - There were some big gaps around the power connector of his right lightning claw, and I think that a whole little piece of detail is missing under his right arm. I won him as part of winning the Tale of 2HD Gamers at Two Headed Dragon.
The only thing I really did other than the paint job was the decals. Standard army badge on the left leg, and I found a yellow winged claw with a tiny S rune in the wing on a sheet of chaos decals. You can just see it in the leftmost pic.
It's nice getting to play with the SM named characters and using the various chapter tactics. Shrike is the third special character I've used. My Novamarines includes a 'counts as' Telion & Tigurius. Using Shrike has whet my appetite for some assault terminators. Also making me think about painting another special character. I have a Cassius conversion for my Space Sharks and a Pedro Kantor model (with 15 Crimson Fists painted already) available. NO. Must focus on wargs. Arrrggh. Oh and I just realized I haven't written on his purity seals at all, better do that now!
