It is a very great work! I create 3D-models of sailing vessels. This is one of my favorite themes! Additional, the Bronze English British guns, Borgard and Armstrong, I have researched for 2 years (EDIT: Because my first vessel is the Sphynx). Spend more than 3000 EUR in books and studied / reworked / researched the proportions and compared it to close to all given sources in the books or libraries. Today I are close to 99% right shape of its real pattern. The 3D-visualization in this century in a gameengine is what my content relfects.
