Silent Manga Audition seems to have a scriptwriting audition. I'm considering the idea of mainly working on those, so that I can spend my own time improving my artistic abilities free from the pressures of conforming to a manga standard.
For those who've seen my art style, is differs from manga in a few ways, being closer to Manhwa ( but not webtoon necessarily ) from back in the 2000s era.
The main difference is in the color palette, but also how I draw faces. But submitting scripts will free me up, while getting my name out there.
