/ic/ - Artwork/Critique

I'm not exactly a full blown beginner, how much time would you give me now before I eventually reach an higher enough level (average mangaka/skilled and popular social media artist) judging from my current artwork?
What I want to improve for now is manga-style inked character drawings and NSFW art, with enough detail and draftmanship behind (one thing I dislike about my art is that it's too simplistic and even symbol-like at times), and I've been slowing working toward it those days despite being able to only draw around 1 hour or less due to attending a job course. Note that I'm not referring to how to study fundamentals and the likes since I know I'll need to start studying them religiously, I'm just looking for tips, thoughts and harsh critique.

My long term plan is first making a name for myself online as an artist, then release the first chapter of my first actual attempt at a comic (as in serialized and in chapters, not funny single pages with 4 panels) between 2025 and 2027. I value both good illustrations and good storytelling, but I'm lacking too much for my standard with the former and just started studying the latter very recently.

For now, the artists I've referenced for my style enough to actually call them influences are Hiroyuki Takei, Philippe Druillet and Kazuki Takahashi.
In regards to furry shit, I especially like Gaku (@quququl_) and Kokimantarou for lineart and form reasons.
I was also a fan of CaptAnaugi some years ago, but now I'm better off aiming for higher (not to say the dude's bad btw).
I'd say I'm only starting to get an idea of what I want to draw like pretty recently, and even then my technical skills don't match to even what I perceive as decently but still averagely skilled by art standards (as in, outside the standards of this board)
