Huhuhu, thanks
It mainly depends on what I'm drawing and intend to use the picture for when it comes to what program I use, but the most common ones are MS Paint, Photoshop CS, Photoshop CS5, Illustrator CS5, Paint tool SAI and the Chibi painter on
[ CS ]. And whenever I feel like just playing around with programs I'm not very good with I usually turn to Art Rage 2.0 and some random apps for my iPad
(sadly I don't remember their names atm). :3
