Are you sure that hull shading is correct? it looks as if you have a transom stern in front of your rudder, and the skegs for the propellers have the same shape on the connection point with the hull but the hull is near vertical on the inner shafts according to your shading, so it can't be the same shape of connection? Either your shaft entry points are completely wrong, or your hull shading is. The shading also suggests an extremely blocky midship section, which I doubt is accurate.
Speaking of shading, what on earth is that shading on the funnels, barbettes and secondary gun turrets? You have a shape somewhat like this if I interpret it correctly:
Aren't those surfaces supposed to be round? I could understand a single highlight being used as is sometimes seen, but this looks like wallpaper with bubbles behind it.
Your first 'deck line' above the waterline is also something I cannot find on pictures (

The armour belt shape is also not something I can find back on the pictures.......
Might I recommend a comparision with some pictures of the ship? I suspect your reference artwork was not entirely correct, it should be possible to fix this and make it an excellent drawing, but it will take some work.
