Oh, wow! This is a very awesome panel. There is so much attention to detail!

It would be great if you could make a living with manga someday...as someone who is also interested in drawing manga (although I'm not nearly as skilled as you!) I can empathize with this dream.
Here's an idea: Perhaps if you are able to complete the first issue (or even first chapter?) of a story you have in mind, you can get some support through Patreon to enable you to continue to work on future volumes...like an online self published manga?
I think it's feasible if enough people enjoy the first issue :) You clearly have skill, so I think something like this might be a feasible option for you-either way, this is just some idea fodder-hope it gives you some hope! I hope you keep at it >w<

It's a great advice. I'll keep working on it >w')/
