Can I rant a bit? Ok, then...
The 3 sci-fi generations were for a bounty I lost. Well, not everyone can win, I get it, and it wasn't me deciding, but... The OP asked for the zero suit, and for a ranged weapon (and that's why I found a couple of hand-cannons in the archives of the danbooru tags), without even telling the setting.
And then the design that won was without suit, with a gun that resembled more a floppy lightsaber, without perspective and hand coordination (judging by the pose and the clipping hand through the katana hilt)...
I found all of this very meh. Next time someone ask, I put a James Bunny there and call it a day.
(yes, I realized only now I made Bunny, James Bunny - with a claymore because I can)
