An online comic book. (Concept art inside)

[Synthetique]

Me & my friend's goin to start an online comic book.
Today i was sketching some to find lead characters. Havent got to anything yet though.
Take a look if you like and tell me what you think of the style of the different characters. I'm going to use the cartoony style in our comics.
They will be in both swedish and english.
well.. gotta go. Thanks for any comments. Feel free to crit.
