"project 186" soviet armored gunboat

this is a game asset 3d model I've made a long time ago for a browser game called Gunfleet. Later I decided to make a render based on it. I've put my effort on the environment and kept the ship topology as it was, lowpoly and creepy (the texturing did the trick anyway)
here's some boat characteristics
