Hey Steven,The armor idea is gathering speed, I see - there is something increasingly sculptural here - indeed, I'm reminded of Brancusi and especially Umberto Boccioni...http://www.simplyartonline.net/the_unique_forms_of_continuity_in_space.jpg
Hello Steven ^ ^ Have you thought of researching the 'Ood' from Doctor Who? With the tentacle-based mouth parts and all that? Might help you with some of the jaw structuring and what not :) SEE YA!
Also, the idea that your creature's shell is as one whole, maybe have a major section of the armour as one solid mass? If movement is then an issue then maybe have it as a protrusion of some sort? Check out the Stag Beetle's antlers maybe :) Structural the antler can be transformed into a more appropriate material like coral rather then being a direct part of the shell as the antler is to the exo-skeleton of the Stag Beetle :)
Hi Steven! Really like the way you've approached this and as Phil says some of your ideas look really structural which is a unique and interesting way to take this. I like the idea of the shell armour as the predictable approach would be to stick a shell on top of yourself. #3 and the back of the head on #15 grab my attention as they seem to flow and connect as though your hybrid could be actually exist!
I would say the next stage would be to try and develop the feet and hands some more as even though you have done some work on them they seem to hide behind the abundant body work. Actually... do you need to have hands or feet? If not how would you make the hybrid still seem correct? or if you don't want to take the armour approach...does the shell have to be on your back?
