Delaque Cultist

I always liked the idea of using these guys as Alpha Legion underhive cultists, have six painted up working on another 14 hopefully cultists are a bit more useful in the new codex. I wasn't sure if I should keep the necromunda bases or cover over them with the basing of the rest of my army or do a mix of both like they are coming out from underground. Went with the original bases as they are the hiver infiltrators ahead of the legion.
