I considered it but opted against it for a few reasons. The biggest being while it would make the bow look nice it would also make the rear far too thick vertically and also cause the trench to be too thick for my liking. I used the below images for my main references. Still I get what you mean, I think i've gone too far in the other direction.
After some prototyping with an angled hinge to support the bottom. I've come to the conclusion that that the only way to get rid of the space in the trench at the bow of the ship is to angle both pieces. This would make it look way more thick vertically at the back than I'm comfortable with though. Not to mention that a for a model of this size, the structural instability would be way too much (I plan to use a platform stand). Guess I'll just have to pick the lesser of two evils.
Why not just bend the top at the middle? Sure the structural integrity goes out the window and I'll have to basically rework everything but it should work.
And it works perfectly, this should also give me more room to add details to the trench. Might finally get those front gun batteries in now.
