I really love drawing, and I would like to start to take it to another level. I would eventually like to maybe design things for YouTubers, Twitch streamers, etc. I currently have Paint.NET and Gimp 2.0, but that's all I really know about that are free. So what else is there? And please remember that it has to be free because I don't have money to spend on this stuff, especially if I'm not sure I want it to be a career type thing.
