Concept Submarine

I think I'm finished.

After a short try to get more dynamic with two torpedoes, I delete this layer. 

I think its better with some life. Also the jellyfishes are a nice contrast. I'm happy with my first Cinema4D attempt and I had a lot of fun.

Since a long time I wanted to create a underwater picture but I never accomplished. It was not easy to get the right light and atmosphere. With this picture I think it works.

What is your opinion. Do you see any mistake? Let me know.
