Lovely design, I like it very much. Impressive destructive power for its size. I personally like its colors, although, when sharing ship/station parts, a more monochromatic color scheme would increase the interest for it, because then anybody could use it, no matter their own color choices or their level of ambition to repaint things.
One other thing I like to do is placing the thrusters of the base on a easily-removable temporary spot, and fill the space they would occupy with shields, etc. Also, I made something base on this, but I'll continue on that in a private message. Gob job! :-)
