Sounds like an awesome project! I think that You should upload it and update us on through a project here on the site :) I'd love to follow the progress :D
Hey there, welcome to planetminecraft! that reminded me of a quote! Nothing is perfect. Therefore, being perfect is being nothing... and that's a great way to lose weight. But in all seriousness you are not nothing. I'm sure You are a wonderful human!
ah, You see worldpainter is for making landscape maps for minecraft. But really You should find out what You want to do mapwise. when You got something You can upload it as a 'project' and give a download link. :)
