I drew this for my friend Jeyl, a generous supporter my artwork. Regarding the request, I still don't really understand what a Tholian is, other than it is something out of Star Trek.
I tried to capture the "essence" of a female-voiced alien made of random polygon shapes. <3
All told, it is a good rendition, but we have GOT to get Jeyl off his matriarchal obsession!
But seriously, nice drawing - he's turned it into his avatar in AIM so I see it and think of you every day
Their silk is extremely sought after, too.
