You're welcome. ^^ :O Manga? Good luck! *thinks making a manga would be hard*
Yea, it is part of a doujin I wished to make that is dedicated to a friend/fellow DMC fan... I never thought it would end up this long. And not even finished yet. Q_Q
Manga is difficult if you want to be taken seriously as a mangaka. It's not a difficult 'art form', but if you don't have attention to detail and technique, then your art will probably be ripped on by others. If you don't mind that then it's fine, but for me I want to improve always, so yeah, I'd say it's hard... especially from scratch.
I am not a total beginner, but there's still a lot more practice I should be doing every day. My sculpting work takes a lot of that time away from me, though.
