Hi Danni - Although this is getting there I'd recommend looking closer at actual ships for the details. There is still a sense that your design is still in essence a silhouette without specific details / or observations of construction. For example, where would the crew live, stand, steer the ship? Can they climb the rigging? What does the railings look like close up? How do the wooden planks fit together? How doe the 'rudders' mechanically fit to the ship. Are there doors in the sides to view out of? All of those things can be answered by looking at real world examples and drawing in closer or more specific detail.
Note - Also, when posting try to write your views about your design.
