Sazh's "pixel art"

[Sketchasaurus]

I'll only touch on the anatomical issues for now.


Firstly, the Frame:

• The spine is too straight and stiff
  
• the legs arent bending naturally and seemingly have no knees
  
• his left (our right) arm is too straight and shows no indication of an elbow
  
• his right (our left) arm bends in a sort of unnatural curve and juts out unnaturally far
  

Form:

• His arms lack any indication of muscular form or elbow bones, and his left(our right) arm looks like a tube jutting from the side of his torso.
  
• his shoulders don't properly attach to the torso or his arms.
  
• his legs are too cylindrical and don't taper near the joints naturally (if at all)
  
• his feet are blocky and don't exhibit any perspective (or difference between eachother)
  
• his left(our right) wrist and hand look like the end of his arm tube was smeared upwards.
  

practice with drawing dynamic figures would greatly benefit your spritework.
