Hey Olekit, nice ships! I have only one issue with them: the shading style of the bow and stern doesn't seem to match, the bow seems to shade almost everything that isn't close to vertical, while on the stern the only thing shaded is the skeg. What kind of rule have you set yourself to use to choose which areas are shaded and which are not?
I try to draw shadows on the hull of the ship along the contours of the frames indicated in the blueprint
