Have you thought about making your own manga.
Absolutely. In fact, I am currently working on them. All original characters slightly based off of my friends.
I try and do all art and writing myself and I can be very picky about my art so it has taken a while to get anywhere with it...but it's moving now.
What type of manga would you write about?
My manga is highly action but with lots of comedy within it. As a lot of my friends are writers, often times our works can parody each other's. I do use magic but it is rather limited and mostly false-magic created through steam-punk-esque equipment.
People make manga's outisde from just Japan, if you had the choice, would you continue to do manga from where you live or go to Japan.
I would go to Japan. I've wanted to before I got into making my own manga and before I was really into anime.
