Character Design

[Who]

What Joseph said is spot on. Astronaut's head (was, now better), hands and feet are larger than the character's still. Also the astronaut is completely out of perspective of that of the scene's "perspective" . The astronaut is drawn pretty much front on to screen. This isn't necessarily bad especially given the scene perspective, but the inconsistency between characters is an issue. Either pick the astronaut as your standard for perspective and proportion and apply to all characters or make all characters including the astronaut "fit" the same perspective and relative scale of the scene
