I notice you are making certain separate "themes" or artistic styles or whatever for different unit types. Basically, you seem to be shifting to a unique look and feel for each unit based on who made them. You have one art style for human made ships (the "classic" style), another for AI made ships, and one for each of the alien races (zenith, neinzul, and spire).
It think this shift in art is a good idea. It would make sense that each race has different ideas of aesthetics, and that the AI no such concept. Keep up the good work for these types of details. They don't go noticed, at least not by me.
