here here, now I've done your work!
I fixed the gun and lines for you, the underwater hull should be slightly deeper (correct me if I'm wrong on that) and the launcher (that is that thing in front of the bridge) should have more details. Thiel's points should now be adressed, you've forgotten a few
EDIT: a thiel, you were before me this time
to be certain: here above I refer to the previous post of Thiel as well
