Here are some quick sketches I did using photoshop to get my concepts out and start creating sketches based on my research and reference:

First image was only focusing on the hull and its layout. I wanted the poop deck, this is the raised bit at the back of the ship. Through research I have found that most junks have the anchors at the front so the rudder isn't at risk when they lower it.

Second image is my first concept drawing of the top deck of the ship. Again its only to look at layouts and what things could be there as my research is still ongoing so things will change often! but these two images will give me a chance to make the first base mesh in Maya so me and my group can start to plan shots and improve on layouts!

Final Image is more sketches looking at the hull of the ship as I plan to start modeling that first! Was playing with the shape and style of the hull. I based these drawings on my research and references. The first drawing was my favorite as it suited the treasure Junk ships Zheng He used.
