Another dozen hormagaunts are complete - I've finished all of the hormagaunts I own! That said, it's still a tiny fraction of the models I have. While there's 20 gargoyles and a zoanthrope that are only undercoated, everything else (which is probably 80+ models...) have been airbrushed in brown with two layers of highlights, my standard before painting the armor.
There's finally starting to be enough models to look like a proper swarm, and I'm liking the way this paint scheme looks en masse.
