VPN Sub - Model 3 - Rough Construct

This is my third attempt at creating a private submersible for the Whale character in the Hard Fork Series. I have incorporated elements of the first two designs and added features. The most notable change is that the sub is much larger now. There are two stories on the interior: the main floor runs the length of the ship and features the cabins, galley, servers, engine room, etc.; the forward upper floor is comprised of the bridge and communications. It is capable of being crewed by a single person but can accommodate up to sixteen comfortably and for extended periods. I have added an exterior deck so that if there are long periods of occupation the sub can surface and the occupants can get out for fresh air. I believe this model is more synchronous with the character and storyline. This is a rough 'build'. I gave it enough definition to convey the feel but have not really textured it or completed a full 360 degree model until I get some feedback on anything I may have overlooked. It is a far more intensive model with meticulous features like the rails and ladders. Oh! Almost forgot! I also added a periscope.














Any thoughts, opinions, critiques, or ideas are appreciated and taken into consideration toward a final build. FYI - I will be adding 'eyes' to the 'head' of the 'whale'. I tried them as portals but they made the sub feel smaller than I am trying to relate so they will just be a graphic. I am comfortable with the shape and size of the craft and feel that once textures and all elements are in place and scaled it will meet/exceed your discernment.
Was that last line cocky? It reads kind of cocky. It's not meant to be.
