GIMP: Not really good for drawing either, but really powerful for photo editing. I used to use this one, but I switched to GIMP. You may struggle at first, but then you’ll get used to it. Paint.Net: Not very good for drawing, but really good for photo editing. I mostly draw backgrounds and animate stuff with this one. Krita: It’s as powerful as Photoshop, and it’s really awesome! The brush creation is very advanced, has a lot of features I can’t count, and comes with some more awesome preset brushes! You can also use it for animation.

I used to use this one, but since I don’t draw comics that, I don’t really use that program anymore. It also has a cloud service, and you can download brushes and fonts from it. MediBang Paint: If you draw manga/comics more than normal digital art, then you might consider downloading it. You can create varieties of brushes easily, and it even has unique types of brushes(Blur, Smudge, Mix, EdgePen/EdgePen2, Roller, etc). FireAlpaca: This program focuses mostly on normal pieces of artwork than manga/comics. Here are the stuff I used or have used (All of them are free):
