Wow this is really good. I love the interior. The top of the sub looks kind of flat though? I'm not sure if it's suppose to be like that, but it looks strange to me. I've always loved the idea of submarines. I've actually been inside one before when I was on vacation, on a tour. The inside is so intricate. I remember they let people look through the periscope. When my dad was looking through them, I wanted to go next but he was taking a long time, so I kept pulling on his shirt. Eventually I accidentally ripped his shirt (which he had just bought the day before). He quietly asked the tour guide where the nearest bathroom was, walked me there, and then proceeded to beat the living stuff out of me with the plunger. The interior is so cool, though. I love all the pipes and little details you put in to make it look genuine. Well done.
