Not bad. A few pointers: aship this size, with those guns would be classified as a "shore-bombardment vessel", or an "artillery gunship"
Another thing is that, well, u see how your bow forms a straight line? If you want to make your vessel more hydrodynamic, as well as stylish and realistic, you should articulate the spacing of the bricks. check out my Oyster 72, its the best example I have so far of what I'm talking about. Keep up the good work!
