Beautiful.

the dark side effect.

the beanstalks.
For satellites/ space mines/etc I suggest bracelet/craft beads which come in all sorts of interesting shapes. Just paint and mount on flight bases. Maybe use a different type of base to denote stationary satellites.
Again with craft beads for a minefield, use a ring template made from clear acetate and glue the beads to it leaving space in-between to place the ships. Just place on the mat around what you wish protected. Any ship that moves and touches the template is attacked. Maybe mark a safe corridor? I have that on my list of things to make.
Thanks for sharing
