I'm no expert on these ships, but I really like it! The top view is very pretty. Speaking of which, I have a few notes on it:
Firstly, the upper superstructure(just fore of the funnels) doesn't add up in the aft end in the side and top view.
And, the turrets have a lot of multi-hue shading on the top view. It's generally prefered to avoid MHS, so try to create the effect with only two shades.
