This is really a most excellent drawing - my congratulations sir
Other comments aside, if I may add some points?:
Lower hull, I would stick with standard Shipbucket colour, and I also stick with Colosseums standards on shading.
Shading: on funnels turret faces etc. I would encourage the use of light from the bows aft; so therefore a lighter shade than the standard upper works on the forward facing areas, and a darker shade (than standard) on all aft facing surfaces, the way you are indicating this looks a bit confusing. Also, one pixel width for undershading, and not three as I see here
The ladders up the foremast look wrong, narrowing down from wider than standard into thick lines.
On the gun tubes, you are showing a yellow tip? I would band this with a black line
Ships emblems, jacks, flags, these need to be sorted on all our drawings. Cut and paste is not correct as it spoils otherwise excellent drawings. The Black Prince badge looks far to large and fuzzy, but you are sorting that.
But this is a terrific drawing, and again, well done
