Suppressionfire,
Thank you so much for your comments. The frame is 8" by 10" and the sub itself measures a stunning 7.5". There are two reasons i chose to have it that way.
First reason was that i felt that a (sinking) cargo vessel within the frame would be unconvincing as the submarine is/ was a standoff weapon. This close up would feel crowded to me. After that decision was made i felt comfortable with the idea more in terms of "lone wolf" and "small ship big sea" as you put it so eloquently
Second reason was the frame. I could not find a ready made picture frame with more ideal dimensions at the shops in my town or i would have used a more rectangular shape, cutting off some of the ocean.
Basically my goal for this dio was to see if i could "do" seawater. For a first attempt im quite happy with it myself.
