very nice work bezo! I have only one remark, that is that I canno understand anything about the multitude of shades and shapes you have put on your hull and underwater hull. you seem to mix overhang shades with shaping shades of different angles and nowwhere over the length of the ship these seem to match. the same issue happends on the hull above the water, there are some different shades of which I have no idea what they represent. all this together is IMO an issue that degrades the otherwise quite good quality of the drawing, an issue that can easily be fixed by making the shading less complex (and by that, easier to understand or even more correct)
if you need some help with that, feel free to ask
