I like Star Trek. I wouldn't say I'm a trekkie (not to the extent my dad is), but I definitely know a thing or two about Roddenberry's galaxy and I really like the races that inhabit it. But the thing about Star Trek is that it was designed with certain limitations. There's only so much you could pull off on TV in the 60s and I think the alien designs reflected that. Same thing with TNG too, I think. True, working within limits is the name of the game in television, but I'd be interested to see a story (perhaps a graphic novel or something) in the universe that tries to break out of the mold and show us aliens that look a bit more... well, alien.
So I thought I'd try my hand at designing a couple of the aliens in my own way, while still maintaining the same concept and spirit of the species. I always tend towards a more cartoony aesthetic, but I think these body types could carry over well into a more realistic style. So yeah, here's a couple Vulcans and a Klingon!
I was fiddling with an Andorian design too, but I think I may need to read up on them a little more first...
edit: oh some ideas on the designs. The Vulcans overall seem to have a higher cognitive capacity than humans, so it would seem... logical that their brains could handle a couple more limbs and eyes. Besides, more appendages = more alien. S'true. For the Klingon, I didn't stray too far from the original. Made the forehead ridges more like plating. Different head shape, feet shape. I meant to show a size comparison to humans, but think taller and wider.
