my dad and i just finished this collaboration drawing of a griffon.
the basic idea was going away from your default heraldic cat/eagle crossing and inventing something a) savage and b) anatomically working.
we had some research on cat and bird skeletons and fantasized about the concept of two sets of forearms.
the current status of research is summed up in this drawing:
edit: image link corrected
we may wind ourselves up making a pure skeleton drawing to give a bit more information on what is where.
basically, we went the way of adding a second set of shoulder joints on top of the shoulder blades.
other ideas we had were about using a deformed hollow joint housing two joint balls (word?) or using a quite complex joint anatomy to get one joint holding two extremities.
also, we added a birdlike sternum to the ribcage to get enough space for the root of the wing breast muscle (which has to be huge - the beast is going to fly).
another decision was if the wing breast muscle should cover the upper foreleg (which we decided for - for the pure weirdness of the idea) or vice versa.
anyway, this drawing is covering up most of the structural problems we were discussing, while focussing on the shoulder/torso area.
the final creature may look sleeker, as we want to add fur and feathers.
needless to say, we both had a blast designing
c&c highly appreciated.
