I would have to say, for me, Corel Painter is my favorite of all the professional art softwares! Unfortunately it does have a steep learning curve and I'm pretty darn rusty. It's time for me to brush up my digital skills within it again. Photoshop is a close 2nd, it finally caught up with Corel's brushes. Well actually I love both Photoshop and Painter, but it seems like Painter never gets its justified glory of recognition. Today I played around in Painter with this one simple cat sketch, and realized how powerful Painter is...and this is just scratching the surface, it makes little animations too!
