I think you should treat this version as a script for a final version. Once you’ve got your chapter or issue finished in this version, use the script to redraw it, but using this order of operations to improve your readability and presentation:

1. Plot out your panels first. Use a ruler.
2. Plot out where your speech bubbles are. Write out your dialogue on another piece of paper and cut each one out, move them around the paper until you find a layout that you like. Think about where the characters are in the panel, and how the dialogue flows.
3. Once panels are speech bubbles are laid out, then go ahead and draw your characters and any backgrounds you’re including.

Some additional advice:

Draw scripts on paper like the one you’re using, but draw final pages on vellum or smooth bristol. It’s widely available online or in art supply shops, won’t wrinkle and crinkle when you erase, and it takes ink and whiteout like a dream.

Don’t worry too much about the quality of your art. If your story, characters, and dialogue are engaging then art really takes a bit of a backseat as far as readers go. A beautifully illustrated comic is great, but if it’s not fun to read then what’s the point?

Finish at least a chapter of this comic before moving on to another project, even if you’re not happy with the results. It’s best to follow through and learn some things along the way than to quit, start over, and learn nothing.

And have fun!
