Posting a couple of my concept works from Patreon about the internal workings of orekroarks here.
A generalized final and preliminary sketches exploring how the changes in the orekroark flight and torso anatomy work and look. this gives a bit of an idea the kind of movement I'm looking for within this skeleton, and and extension on the direct structure of some bones.
These sketches are some of the concept and reconstruction of orekroark flight anatomy. As an alien creature that walks both bipedally, and quadrupedally... and has the capability of flight, it has been a bit of a struggle to develope a system that allows it to retain maximum flexibility and the ability to fly.
The skeleton has been redeveloped from a very bone heavy structure to a skeleton that has a shortened ribcage with a sternal spoon, and enlargened 3 pronged processes on vertebra that accomodates both the front limbs and the wings in different connective space. I'm still shifting around the shape and sizes of the scapulas, and other parts of the spine and pelvis.
One thing that I tried to add to this design was a lateral semi-rigid, pliable connective ligament net that anchored to the wing's scapula, pseudo ribs and the pelvis, with a ridge along the entire ligament that acts as an alternate space for flight muscles to connect to all the way towards the pelvis. The idea was to maximize the flexibility of the creature (To that similar of a cat) while this net and the muscles connected to it were relaxed without the muscles getting too much in the way of the movements like they would if they were connected to a larger rib system with a stiff sternum. During flight, the net would tighten, which would keep the body stiff and stable for flight, and allow the msucles connected to it to use it like a bone.
Not all of the flight muscles are connected to this ligament net. I've still maintaned some of the connections to the main sternum and the 'flight spoon', which the scapula is also anchored to.
They always need work, but at least they are always advancing.
