I've seen great results from so many titles that I can't list them all. The more common is for the aspiring artist that has no money. For them I suggest The Gimp and Paint.net.
Go get them and try them out. http://www.howtogeek.com/201354/ninite-is-the-only-safe-place-to-get-windows-freeware/ tells where I got my copies.
As the tilte says, I am looking for drawing software that could powerful as photoshop cc for drawing... I mean I see a lot of people using photoshop cc for concept art... The problem is, I am not really likely to buy a subscription fee, because for me subscribe fell like u ever got nothing as u lose everything as soon as u can't pay anymore. The fact is, I know photoshop cc is really a good software for drawing, however Do sombody knows a software that could seem as complete as this one, and really really affordable if its a paid one.
Thank U very much guys.
