I totally suck at drawing and photoshop drawing with a mouse, but here's my efforts:
(hands in a fist, head looking down, legs in dashing backwards position)
(hands in a fist, head looking down, legs in flying forward position)
(palms up, legs together, back arched, head looking up)
(palms up, one leg in front of the other, cape flowing back, head looking forward)
(cheesecake pose)
If none of these work, then my general wants for a sculpt are easy:
-Storm should have her arms reaching out to her sides
-The sculpt should have her floating on the base instead of standing (put some pegs in her back and let her attach to a Sentinel with her feet above the ground, imo)
-As a bonus, it would be great if Erik or Koto would get brave and actually attempt a horizontal pose that makes her look like she's flying instead of standing/floating
