K so I just finished reading Gravity Rises by BrightnessWings19 (originally by @Sophora I think I spelled that right?) and it is GREAT!

It's a Gravity Falls AU that basically is a swap, but on most occasions personalities DON'T really swap at all. 

And Dipper is a precious cinnamon roll oh my gosh

So I drew him and Mabel XD

They're great, and I totally recommend it, but only if you've seen the actual show, because there are some MAJOR spoilers and points that would be slightly hard to understand if you hadn't seen it.

Hope you like! :3
