Heres another rough sketch of my giant squid-turtle, i think i have found a shape i like, the fact that this monster is portrayed big helps as it has big features.
This is the final design i am going with, i think it works quite well!
I have shown the side, front and top view of the turtle, i may also add an underside view later on. I found the idea of a giant creature that looks like it should be in the sea, but is instead, flying around space works rather well, because space is in fact much like the sea and would allow such a creature to move around in much the same manner as it would under water. I got inspiration for this creature from watching "Prometheus" and a show called "River Monsters". Both the Film and Show gave me a very good idea for this creature, because i found that when you don't know what to expect, it often gives more of a wow factor and leaves you wondering just what might actually be out there.
