FireAlpaca, besides being an adorable name, is a lightweight drawing/sketch program that reminds me of open canvas but with a few more settings. It’s got some basic tools and settings, but it’s fun to doodle in it if you aren’t using photoshop.
It’s also free. :U Everyone likes free. And available for mac and PC.
OMG CUTEST ART PROGRAM
I think I’ll give it a try :D *downloads*
THE PRESSURE SENSITIVITY IS REALLY REALLY REALLY REALLY NICE OK
Possible SAI alternative for Mac users!
