Placing this question here to see what others like to use. So far, my preferred art program is Krita, Sketchbook being second, and as for the rest, I just try others out. Gimp, if I remember correctly, is kind of difficult for me set up a view of the picture, and so I do not use it. Practice will probably change my mind. Krita is my favorite, since it is receptive to my Wacom tablet, and the user interface does not seem too hard. It does not take long for one to get started with it. So, what art programs do you people use?
