Thanks for all your replies guys. =D
I've decided on a 16x25cm (roughly 6.5x10") page.
Take some time to flesh out what happens in the story before you get to your characters.
Aye, aye Sir. I've been wanting to start this since last summer and I've had a hazy kinda plot since before then. I know what happens at the very start, and I have a lot of ideas for making up big parts of the story, it's just the in-between bits that separate the big stuff that I need to focus on.
It just means if you mess up a panel, you won't have to start the page again and also you can decide
how big each panel needs to be and just resize them on the computer.
I'm kinda gonna do that. My plan is to roughly sketch out the panel on a rough layout of the page but do the drawings on a bigger sheet. I've tried drawing within a box and it just doesn't feel right. Like trying to do a close up of a character... I'd rather draw the whole head then trace the part I want into the panel.
And I'll pencil it all out on the page and ink it on the computer so I won't have to re-do it all if (when) I cock up.
I have Manga Studio 3.0 which I've yet to use but I've seen a few tutorials on the web and it looks awesome. I just have to learn how to do it... =/ *gulp*
...just remember to do some page layout thumbnails before you do this, otherwise your pages could get too wide/tall/cluttered with panels.
I do have layout thumbnails for the first five pages. =] I won't post them in the Manga WIP yet though 'cause it'll probably be a month before I do anything else worth posting in there! =P
One of my characters is coming along though so I might have a page of him up soon. =)
Thanks again guys. =D
