Sailor Mercury's design has to be the best. However, I feel that there's two parts missing. For starters, she doesn't have the sailor part around her neck, you know the one. The second, and this has to be the most important, there's no life support pack filled with oxygen and hypno gas. X3
Honestly, I was thinking about the collar when I did this, and I went with this because I wanted to acknowledge the collar, but I really didn't want it there. So I had her uniform collar kinda in the suit. I saw the others done with the collar in their own way, so I went with my way. An actual physical tank just slipped my mind! Whoops!
Also, sorry if I sound incoherent. Been up all day, roadtripping. Just got back so I am just blah minded.
