Wow, these look super, SJ. You are very creative!
Some really cool sets you have there.
Your diorama makes me want to go out and buy that giant black octopus. (Another thing to add to the never-ending list!) It looks even better out of the box than I expected it to.
I like the way you have used reflective material to create some of the water. Is it a sheet of plastic, or something else?
