Much better. Still not loving the neck, but if the ship has shields it works. I do like the radiator panels. And now that the guns are a more realistic size it works better. But they are still massive guns (lets face it, if the thing is ISD sized any recognizable guns in that position will be big). But I do like the looks, and the guns are intimidating at that size. Now personally I would say it is more in the corvette size range...maybe 400 meters? That is what I would call it any way, if I had guns that size compared to the rest of the ship. Again, good work and I'm looking forward to seeing more of this. And don't let my complaining about the guns get to you, I actually like them...I'm just tired and that makes my typing come out like that.
It's quite alright. I'm sorry if the neck bothers you, but I figured the crew would appreciate me keeping the main fusion drive as far from them as possible. Also, it provides room for the habitat module (the bar-bell thingy right behind the gun turrets) to fold down flush with the hull during acceleration or combat, I just haven't yet figured out how to model hinges for it yet.
I should explain that my ship is being designed with the assumption that neither energy shield or artificial gravity technology exist. Therefore the ship needs to use either spin or acceleration to simulate gravity for the crew.
For passive protection, the ship is armored similarly to a tank, with the best armor in the front. Active protection would be in the form of point defenses and ECM.
People here like to make big stuff, and no mistake! It in no way looks like an improbably huge starship though, and is unlikely to unless you add an absolute ton of detail to it. Right now it looks like the start of a ship less than 100 meters long, and even then it needs more detail to start looking convincing.
As I'm learning, scale is more than just numbers. I'll see about trying to make the ship look as big as it actually is.
We see a lot of beginners build very basic models and call them gargantuan colony ships lightyears in length, and no one thinks they're anything other than a couple of boxes. I think you'd be better off building something like a fighter or shuttle, small enough that you can practice making a model that will actually end up looking good with a modicum of detail. You'll feel better about it as it will look better and you'll maybe finish it, whereas making a ginormous blank ship does you no favours. Its great that you've taken up 3D work, it really will let you do amazing things when you get the hang of it, but I'd suggest walking before you run.
I'll definitely try making a fighter design, I actually have one sketched out on graph paper. However, this starship has been in my head for years, it's only now that I've been able to actually see it. It's been a lot of fun adding details to it.
Details like maneuvering thrusters and minor texturing from Sketchup's stock library.
