Update for today:
Since I don't have any good ideas to finish the textures, I did some tbl edits, balancing the ship, it's guns and also gave it a muzzleflash:

The ship (named
Hussar) is a 'heavy interceptor', 18 m wide, 19 meters long and 13 meters high. It has almost the HP's of a GVB Sekhmet, it's a bit more maneuverable, much faster on A-burners, and carries a lot less missiles (20+30 in 2 bays)
It's primary guns (
Koncerz, named after the big sword the hussars used) are almost 2x more powerfull than a Kayser, and suck a respectable amount of power too. The Koncerz has the 'cycle' flag added, so only 1 gun shoots at a time.
Again: Suggestions, comments (other than the detailed textures I need to work on)?
