Hollow Knight au version of Nathan, finally

I recently picked Hollow Knight back up and stubbornly keep making myself play until I get better at it. It seems to be working!
I've loved this game for so long and I've been mulling over how to translate Nathan's demon form in the game's style and design senses for a long time. I think I've FINALLY gotten something satisfactory!

For funsies I thought up what kind of npc he'd be too.
Basically he's got a tummy ache from gorging on too many wandering husks and other feral bugs, so all he really does is whine about his poor sensitive tumtum. If you offer him a rancid egg, he can't help himself and slurps it right up like the dang glutton he is. This of course just makes his tummy more upset and he ends up horking up some items the husks he ate had. (geo, mostly) but the last time he lets himself eat a rancid egg, he spits up a mask fragment and then will refuse to eat any more, having learnt his lesson.
