Earlier in the semester I read the first book in C. S. Lewis' Space Trilogy titled Out of the Silent Planet. It's an awesome book and I can't wait to read the other two. I wanted to come up with designs for the 3 alien races featured in the book and this is what I came up with.
You can read the basic descriptions on wikipedia here
I just wanted to establish the primary forms and anatomy of what these creatures might look like. The descriptions are really cool, but in some cases I was a little bit intimidated because there are a few things that just don't sound cool. For example, the seroni (plural of sorn) are described as having droopy noses, and that is really uncool, so I tried to come up with a nose that could reasonably be described as, at the very least, LOOKING droopy, but still had a neat and not-dorky look.
These are just sketches of me trying to get my initial concepts out of my head and on paper. I'm planning on setting some time aside to go in and dig a lot deeper and develop them a lot more.
