I don’t want to come down too negatively, but when posting for artists your writing is the only thing an artist will have to go on. If you’re serious about tempting someone to team up, it’s important to slow down and check your work for typos and missing words. It just shows professionalism and that you take your stuff seriously, and that you’re a writer.
Do you have any sample pages completed that you could show that give an indication that you’ve got a handle on dialogue, and the kind of stories you produce?
I only mention as a lot of people post requesting artists and they get no responses. Getting an artist to devote time to a book is tricky at the best of times, and attention to detail and putting together a thorough introductory paragraph will help you out lots.
