Undertale - The 6 Human Souls #1

So I was thinking about some concept art for the 6 human souls Asgore had already taken.
I find it interesting how many people think they must have all been children, but I'm not too sure about this. I don't remember anything in the game telling me they were only kids.
I guess, since Frisk is able to equip everything the previous fallen humans owned, most of the things must have been kid-sized, like the gloves. Yet the pan and apron combo don't have to fit... btw I find Frisk in a too large apron adorable as f.
So now I'm kinda holding myself back at drawing more sans (stupid fan favorite already XD) and am doing this stuff. Expect the others to poop up in my gallery over the next days.

EDIT
I made a rough sketch of all my concepts. Enjoy!
