I really love how you nocked out the anatomy and biological details so thoroughly. are you able to produce stuff like this with enough ease? if so, i MIGHT have a job for you later. (it includes designing alot of well thought out aliens)
BONES!?! What is this earthly heresy?! EVEN A VERTEBRA AND RIBS!?!
Though I do have to say, I admire most of your designs (most of which I saw on your website). As we all know, four limbs is too earthly and cliched, as are jaws, yet you can blend the familiar (eyes and mouth on the head) with the alien (alien mouth types and non-earthlike head shapes, and the un-earthlike eyes which the untrained Human eye cannot even detect as "eyes"). For that, I must praise you.
