Here ya go!
First up is the Hive Crone, i need to think up a good Genestealer Cult sounding name for it. It has a missle rack on top for the tentaclids, a heavy flamer for the drool cannon, and an extended fuel tank on the flamer to represent the S8 raking strike.
next up is the flying hive tyrant. It has quad stubbers to represent the 2x devourers, a Cult Magus to be the source of psychic powers and synapse/shadows, and the cultists with powerfirsts and power axes to represent the close combat attacks.
Thanks again for the stormtalon engines, as they fit perfectly! Let me know if you want to get in a game against these awesome beasts!
