I really wasn't going to make a full comic in the first place. I only wanted to just make a comic page to see how I could tackle the process because I wanted to try different art mediums. Beforehand I was trying out watercolor painting (which I am sticking to).
I decided to plan out one page scene Involving a girl I was going to name Pea complaining about another boring day. She goes about her mundane task and gets on a city bus for work and then as soon as she got off the sky got dark and she smile because she knows there's trouble afoot. Then a large monster was supposed to appear and then she gets all super powered and attack and stuff.
Well...since my brain likes to add on and fix things about raw ideas Pea became Tameka and then I begin to develop the small premise into a full story within a bigger story that I've been working on for a while now.
So I made Mercenary Bound to be a standalone comic to help expand the universe within my novel that I've written. Even though it's in the early stages I think this is really fun to do.
Oh and I found Tapastic by rummaging around deviantart and that also helped trigger making a comic, so a lot of your comics have inspired me to do so as well.
