Is that bubbles comming off the stern, has it sunk already??
Those "bubbles" are the little that's visible of the aft mast. Not very pretty... But it's not a sprite yet, just a 3D model. Turning the 3D model into a sprite is going to be tricky, as I'll have to figure out how to make a decent-looking wake for the moving animations. And nice puffs of smoke coming out of the funnels. And shooting guns. (Why do I get myself into these things?)
The Bridge looks good, but you just might want to decrease its height, as most pre-dreadnaugths had pretty low bridges because there was just one gun fore and aft.
Also, single barreled secondary turrets were common secondary armament, as sponsoons were pretty much eliminated by WW2.
About bridge height, I went roughly with the line drawings of Schlesien in 1945. What I was talking about is the nice big conspicuous glass panel. I wouldn't want to be behind that thing if the ship was being shot at.
As for the secondary armament, I'm not sure what sponsoons are anyway... I was thinking of using single-barrelled turrets, as I didn't feel like cutting holes in my nice hull. Or I could copy that crazy american design with the secondary turrets perched on top of the primary. (Kearsarge, was it?)
