Hi @ZPKinc, welcome to the forum! 
Alas, all good things must come to an end. We’ll have to do another CAD competition at some point - this one was quite fun, and interesting to see the responses. We’ve featured several of the submissions on our social media, which you may or may not have already seen 
Cool design! Given the big water hole in the middle, presumably the electronics would live in the outer shell, perhaps with adjustable fins at the rear for steering? It may be tricky to get much buoyancy, and to balance the weight distribution, but it could also potentially work well as an efficient vertical travel / fluid-filled-pipe inspection robot or something
Design wise it’s kind of like a mix between a streamlined torpedo and an extended version of the donut concept in my StaROV project
