So for the longest time ive been using a program called My Paint. It's free but the only downside is that i'm stuck with endless canvas (meaning i have to open MS paint to resize and crop) and the other problem is that i cant section out or rotate specific parts of the picture, Other than that i love the brushes it has to offer (My Paint) With Sai though i'm not sure if its just from the trial but i literally have no brushes to work with besides a janky blur brush and 6 paint brushes that do the same thing. So if anyone here uses Sai and knows theres more variety lemme know before i drop in money for it cause i need the resolution presets and the ability to section.
