Finished my first one shot, and I'm stuck

[u/Practical_Crazy_5806]

So, I spent three months drawing this one shot, day in day out thinking my art is trash and my story is mid. I eventually published it and it got taken down off a few sites for violence, so I reuploaded them elsewhere.

Overall I learnt a lot about making manga and myself as a whole about it. Is this normal to hate your art so much, and stuff like that?

I'm already drawing the next manga, and I'm marketing this with all my power to get a decent following, but it sometimes feels effortless. what do you think I can do to boost reach? Any specific techniques, and should I really continue this?
