This is great! Her bent leg looks very awkward, though, and it throws the entire pose off considerably. Bringing the knee forward to support some of the weight would help a lot with that. I'm in love with the background, and the colours you used-- there is so little great drow art produced lately.
Awesome! My favorite part of this has to be the matron. The detail on the chain mail, her crown, that hook weapon, and that chitinous looking armor is just fantastic. I'm also loving the way you did the spider webs. They just have that look of soft thread, but also that they're sticky.
My one critique would be that something about the spiders (mostly the smaller ones)looks more beetle-like than spider. It could be that pattern on their backs strikes me as something I would see on a beetle.
