An idea I had in mind for so long but I never had the courage to actually draw a full Noivern until now. (the one time I did draw a head for Leo's ref wasnt exactly good XD)
But yeah, I always loved Noivern as a Pokémon and I think it really lacks some fart art.
In my headcanon, a Pokémon which "can reduce a large boulder to pebbles" with sound alone is more than capable of farting so loudly that it literally shakes the walls.
This is exactly what happened to this trainer here, who is everything but pleased about how his room looked like in the aftermath of Noivern's little "accident".

I'm actually quite pleased with the outcome of it. Of course there's quite a few things to improve (I really need to practice Wings XD) but in the end I would call it one of my better works^^
