Done. All that remains is a matter of finishing. I want the hull to have a somewhat shiny surface since the ship is supposed to be a shiny silver colour or almost like buffed bare metal. And I think I've found a way to add lights within SketchUp.
More X-ray views (cause I think it's kinda cool).
It's hard to tell in these images, but I have added the periscope/telescope to the main compartment. Like onscreen it's located on the port side of the main cabin. I obviously could have gotten even more detailed with the interior, but for this first time around with this design I don't see the need. I thought about adding detail to the back of the access hatch since when it swings down (as it's supposed to) there would be ladder like steps affixed to it. I might still do that if I decide to show the ship landed with the hatch open... Okay, who am I kidding? I know I will eventually do that.
