WOW! This is a really inventive application of pneumatics. I wonder
if the number of mini-cylinders could be reduced by 10 by only using 1
on each leg (use 1/2 beams for bracing outside the cylinder) and maybe
using single cylinders and links for moving the legs?

The basic design has a wonderful symmetry that makes it look like it
should work. This is a basic requirement for many robots - if it looks right
it probably is.

Anyways, my tendency is to try to reduce a design to bare essentials once
it is working - but since it's your design, I'll leave it to you!

Great work!!!!
