Well I can come up with pretty much any character on the spot. My issue is that, because I love creating them so much, there ends up being too many. Then they get scraped because they've got nowhere to go.
I'm a pretty grounded writer, I edit for most of my friends and enjoy keeping them on point. lol
If you give me a day or two, I could come up with at least three characters: designs, names, backgrounds.... I'm all about character development. The more development there is the better because it just makes me love them more.
But I also like to create "babies" with people- characters we create and share equally.
I like fantasy, decades like the '20s and further back, I've dabbled in future-istic science fiction robot wars before too... So pretty much, I enjoy everything and can feel confident about writing if I have enough research to back it. Anything based in real-life type situations, that is.
With fantasy, I find I can make up history, magic, and countless other things.
I hope this isn't too overwhelming. Or confusing. Haha.
