Astrum Well, I would scrap the FTLS, they cost too much, unless you want to make it for Bounty Hunter, then it's up to you.
Back armor isn't really necessary, missiles can't attack your back as it is right now, because of changes on their targeting and maneuvering.
Engine part definetly needs a re-work, modules are actually pretty good, good job on that part, but maybe remove some armor all around, mainly on interior, that's generally what I do anyways.
Also, yes, you should try to make it with different angles, experimentation, in the end, will give much more information than what we say, after all, how do you think that we know this anyways? XD
