That looks great Cinqnic although I agree with the nacelle pylons and the fact that you said the engines need more work, a bit thinner a tad longer, could do with bringing the hull scoop out a little further forward with the pylons and extend the secondary hull section with the shuttle bay in a little further aft. I think if the pylons came out flat and level like the ambassador to start with and then up a 45 degree angle from there to the engines which also in the original design are angled at 45 degrees so that they are the same as the nacelle pylons. I think too that the engines need to drop down a fraction.
I love the darker texturing on the saucer it makes it look like its got armoured plates. The bridge looks a little on the large side considering the ship is only a fraction thinner across the hull than the ambassador and the shuttlebay on the saucer is all one bay, but like the sovereign class that has three doors that interconnect across the shuttle bay, the falmouth has two doors but unlike the sovereign they dont interconnect, it has that pillar in the middle within which is the flight control room, rather than being at the rear of the shuttlebay like you see on the connie class in Star Trek 5. Behind this pillar the shuttlebay connects up, with just a catwalk down the middle at the top deck of the bay connecting the pillar to the rear of the shuttlebay, it can also be accessed by a turbolift that goes up the pillar and allows access on to the bottom of the shuttle bay from the base at the rear of the pillar also. This is how I envisaged the ship anyway, I've spent a lot of time thinking and drawing it at home, I have many different sheets of paper with ideas on and rather stupidly have become extremely attached to this design, I am also in the midst of writing a story that is based around this vessel and the lost era period.
I definately would like to see the pylons and engines like I mentioned just to see what it looks like if anything, if it looks wrong then it?s all part of the designing phase certainly slightly lower the engines though, looks too much like the TOS connie with them up that high, meant to be more like the excelsior in proportions than the ambassador chunkiness, although there is nothing wrong with the ambassador I love it.
Another thing for the engineering section looking front end on at it I think it should not be entirely circular but more egg shaped with the thinner part being at the bottom again keeping part of the excelsior lineage it being u shaped from front profile, its just adding a rounded section to the flat part.
Finally I have decided where to put the last two forward torpedo launchers If the nacelle pylons are bulked a bit around the root on the topside , where the pylon meets the hull, slightly pod shaped like you see on commercial jetliner aircraft (although the commercial jetliner pod section are on the underneath of the wing to accommodate the landing gear) and mount them within that. From head on it would look pretty mean two on the lower section of the neck two beneath the deflector array and one either side in the nacelle roots, I?d say it would look off putting from a Cardassian cruisers point of view from the lost era period with that bearing down on you. I like the ambassador frill that goes from the pylons around to the shuttlebay opening., although I?m not a fan of the Enterprise C touch to the underneath of the aft shuttle bay with that even smaller shuttlebay, that just looks awkward to pilot into.
Going back to the Phaser design I think I prefer the smaller array sections around the ship, It would look a bit Frankenstein with both.
All in all this beauty is beginning to look marvelous!
