The underside of the nose is a little.. weird, with only those inset polies.
Looks great otherwise. Unlucky Soul already has a finished Bret BC model which was actually decent, but I'd be happy to put it to a community vote when this is finished.
I am not really sure about this one. It looks like if you did this to the Essex, but with a Crecy. The result is "kind of" okay, but it lacks character. It's just an average between two ships. By character, I mean that Vernian steampunk atmosphere, the Gothic arches, the castle battlements, the glum feeling which it effuses that gives you the impression that whoever designed its appearance did it while it was raining outside, but also the sophisticated ornaments that, besides showing who holds Dublin, scream in the melody of an aria by Thomas Arne: "This is a nation with a history! Rule, Britainnia!" It is a killing machine, but one under the employment of her Majesty. What I think is the core of the Bretonian style is majestic formality.
My advice is not to look at other ships for inspiration, but at what inspired those other ships in the first place. Do it while listening to this.
These are some of the things that I sent to @Unlucky_Soul while he was making this, or would have sent:
Bretonian design is the toughest to get right, as Soul said, but when you do it, it is a work of art. Like Soul's carrier.
PS: If you chose to stick with your own current design, which is okay and entirely your choice, then I advise reducing the number of windows and increasing their size. As it is, the ship looks larger than the Dunkirk.
PS 2: Apparently there is another problem. I don't fly battlecruisers, but the guys in the BRF| do, and they say that the ship, although it looks pretty, is too fat to be good for PvP. It would probably be even fatter than the Rheinland battlecruiser, which means that it is quite dead to Valors. Or anything else.
