I have finished the sprites for all the units (shown in Ulthwe and Iyanden colors). While I didn't do all the weapon options for the Hornet like I did for the others, I'm ok with that. I think in most circumstances people would go dual pulse laser anyway.
Ultimately I've created options and really that was about the main goal. The above shot shows all the units in two different schemes and shows variations for some of them (weapon types on the vampire, lynx, etc). If someone were intent on recreating a game of Epic this force is ready to go, or for 40k, in which case there are some extras.
To be completely honest it always surprised me that Forge World didn't release a Storm Serpent or Void Spinner. They seem like pretty low-hanging fruit and real no-brainer conversions with the chassis available fromt the Cobra and Scorpion.
