Story Concept - Characters - Part 1

I got the idea for a story...thing...but I will probably never turn it into a comic so I will just submit the character designs.

The story takes place in a world where you cannot die until you've reached a certain age, also there are demons and blah blah blah. If you are killed you just live on.

And those two are the main characters, they are twins, and once they had the same height. But that guy (names will be added later) was afraid his sister could grow taller than him, so he cursed her, not knowing that there would actually be a curse keeping her from growing taller. Obviously she was not impressed.
And now they are just wandering around, like if they would find a solution to the problem by a coincidence. And of course they meet some other weird people (character sheets following later), the usual stuff.

Tried another drawing style for this. (a bit inspired by the anime series Katanagatari which I watched lately and can really recommend)
Their hairstyles and clothes are supposed to look weird.

Characters belong to me. Please do not use without permission. (as if anyone wanted to do that...)
