Second that.
The second picture you posted (as well as the paper model) show that the forward edge of the bridge falls somewhere between the first and second portholes.
And now you'll have to figure out the shading to make that part of the bridge look rounded, too
The funnel might be a bit thicker too, but that's a tougher call.
Is the ship closely related to other, better documented classes that you can confidently draw the lower hull?
Still and all, that looks like a good start, much like your previous posting.
Maybe that's just me, but may I suggest coloring the complete hull a shade lighter? That would make the relief shading and any details you may add more visible.
If you're interested, I suggest looking at Darth Panda's latest postings in the
submarines thread for some examples of a dark grey/dark red combo that leaves some margin for details.
Of course it's your drawing and your style, so I'D understand if you choose to stick to more realistic colors.
