I wish, that is specifically something I'm still trying to learn myself! These are some of the lessons I've learned, maybe you can get something out of them:

- crazy/weird panels are fun and look cool, but lose impact when used too frequently.

- include speech bubble text early in the sketching phase so you can work around them.

- getting something out of the way by squeezing a lot of panels into one page is tempting, but it's usually better to have fewer bigger and clearer panels, especially if you need to visually explain something clearly.

- during speech-heavy segments, some panels with little to no text can help with "infodump digestion", similar to how blank lines and one-line-paragraphs can break up a wall of text.

- Just how you preferably end a sentence in a speech bubble instead of splitting it up, it's usually best if an action doesn't begin in the last panel of a page and continues in the first panel of the next page. In a case like that it's usually better to move that last panel to the next page and either resize the other panels on the current page or add a little filler panel.

Hope that helps!
