In a comic page, consider each panel a full picture and charge accordingly. For example, if a page has a panel of two characters, three headshot panels, and maybe a medium, then charge what you would for two characters, three portraits, and a medium shot.

I recommend adding a page discount on top of that (25% or so), but if you feel extremely unmotivated to finish a project, you've probably charged too little. I learned this while I was taking $10 per page once.
