Nice start...
Now for next round of updating the drawing, take notice of these points:
1. Overlapsing black pixels. NO NO and NO
Shipbucket style basicly relies on drawing everything thin and small with three pixels: two black one surrounding the grey... Your mast, cranes, funnel caps... they have no excuse to be drawn badly, and with relatively small add-ons, the drawing can actually start looking good.
2. The use of colors in the hull. Drawing the actuall hullplates is overexessive, you cannot see the plates when looking ship from your own eye from the distance that the shipbucket scale presents. Only considerable changes in the thickness of the surfaces suffices to be presented. Such as armourplate. If you want to make your drawing look good on the platewise, I suggest browising the Italian folder of the mainsite and see how Lazer_One has worked with the armourplates of Italian cruisers...
Also, the idea of Shipbucket's colors is to use same range of palette upon any given color. When we drawn something with grey, it doesen't mean its actually a grey in reallife... only that it apperars to be grey when looked against its background. Naturally, when there are surfaces that are not grey, same rules applies, you just need to use spesific color palette of that background color: Therefore, you cannot drawn the underwater part of the armourplate with same color as in the upper hull
3. Crediting: In Shipbucket, we credit the thing simply by listing the names of the artist in a colum underneath the name of the ship. The orginal artist comes first, then followed by the other artists (like Clonecommander shows in his post)
