Question about Gato submerged configuration.

[The Kraken Wakes]

Hi,
I think your attention to detail is fantastic.
This is probably obvious to a man of your experience, but make sure the diveplanes are correct. Likely to be extended if submerged.
A kick on the rudder might make it more realistic.
Perhaps some patches of rust ? Bow caps open ready to shoot, or shut ?
A torpedo just leaving the tube ?

I have an aquarium model I want to build but no idea where to start.
You remember in the Godfather when Sonny says "What's this" as he unwraps a parcel of fish wrapped in a bulletproof vest. And Robert Duvall says"..it means Luca Brasi is sleeping with the fishes"
I want to have a little gangster figure wrapped in chains on a bedstead. Then I put it in the aquarium. Ideas for making this ?
