Re-ti limbs brainstorm

A mosaic of several pages of sketches of Re-ti limbs, from the basic structure and muscle architecture to possible arrangement of limbs, details of the distal areas and bits of skeleton. Re-ti ended up with all “hind limbs”; unlike Earthly quadrupeds whose fore and back limbs are mirrored, it has eight limbs and all of them are the same structure. It also has elbow-like levers on all major joints, its “toe” bases originated as floating bones parallel to the “tarsus”, and it has a hydraulic limb skeleton in addition to the bony one. And its extensor and flexor muscles can be intermixed on the same side, unlike in vertebrates who have them on the opposite sides of the limb.
