Those digital glyphs on the barrel armour are a fascinating detail. Reminds me of the binary symbols in the Arecibo message.
A brilliantly functional but somewhat unearthly design. Well done again.
I agree about humanoids. There's nothing wrong with humanoids--some of my best friends are humanoids--but I do like to see other designs myself.
As for your question, I'm afraid I don't know of any xenobiology groups--not that are active or accessible. It's been some time since I've looked, though. And thank you for the compliment! There's a lot worked up on the galkgrokst, and I'm glad that sense of depth comes through here.
