|Heresy-era Son of Horus from Index Astartes|
These pics also show the height comparison between the beakies and the current models-- the slightly bulked up bases did the trick.
The jury is still out on which way to go with these guys, but I'm leaning towards the Sons over 'normal' Black Legion. I think they will look better when they are done, plus the counts-as options really appeal to my sense of efficiency, lol. Drop me a line with your opinion on the color mixes, or paint ideas that might represent 'sea green' but still look good en masse.
