I am definitely thinking about specific ideas and how something would grow and evolve in an alien environment, and thinking about what function all the forms i am creating do, but i would say a larger part of thinking at the moment on a lot of these are more form/sculptural exploration for sure. Trying to go in and just have fun creating something interesting based on the design rules set up by earth based animal life with a very free and open mindset, don't want to limit the forms by setting too many limitations at the start..... that's all the 'work' I would go back later to figure out the skeleton/muscle system which will ultimately change certain aspects of this but i will get to that at some later point after i finish a first pass at the initial set of creatures.
