Here is my out of your comfort zone entry. When I first got this topic, I thought it would be a breeze, but when I realized all my light-blue bases and clear pieces are in a Giant WIP, I was troubled. After a lot of thinking, I used a big base plate for my base, and tried to cram in some details. I think it came out good! What do you think?
About this creation
Heres a big Pic of the whole MOC. It shows a researching submarine emerging from a cave entrance, seeing a sunken ship surrounded by fish and plants.
This is a good underwater scene with a lot of cool details. I like the fish, sub, and ray, along with your coral and rock formations. Good work using parts in unique ways to create a lot of interesting components of the MOC!
