man, i like your sprites a lot! i feel with some of these animated ones you could benefit from maybe just 1 or 2 more inbetween frames so the silhouette changes aren't as jarring– especially in transitions between similar-coloured cluster areas like the hair/jacket. you have really strong mecha design sense, and the lower half feels very strong here with the simple motion, but the softer materials feel a little too stiff while moving. keep up the great work and keep making cool sprites!
