Ok, so lets be fair, i've been quite anal bout this ship, making sure i got things right or not, NOW i actually had a chat with Rich Sternbach, he has confirmed that i was correct the back area is indeed a Torpedo launcher, so Happy me away i went with today's modeling, firstly i thought the head was CRAP so i decided to redo it, this is the result, First picture is the underside head deflector array

Front of the main bridge

Aft of the main bridge,

as stated the whole head is new, but i will be adding more detail as i go, it just looks a bit bland at present, but it will improve i promise

also the front Top area of the neck was a bit boring i though, so i deleted all the face's and spare polys and decided to start it again, and well i was very happy with the result
Before

After

*EDIT*
I don't know if this is good or not, so be honest here please people so far it is sitting at
6,862 poly's
9,900 Tri's
8,317 Vert's
