Am I detecting a bit of an aquatic influence in the shape of the smaller craft? These are actually rather interesting, especially made by a kid.

Concepts of air pressure, escape pods, invisibility cloaks.... yeah, somebody was watching their share of Star Trek/Star Wars. Or reading good sci-fi.

Good job on these! I'd be hard pressed to draw anything this compelling even today. No artistic talent whatsoever, sadly. Thanks for sharing.
