Time to look into Corel?

I did this caricature of Tom Waits in Photoshop which doesn't have the control I'm looking for in digital painting. I have ArtRage and have seen impressive work but I just can't use it for blending. I've known about Corel Painter for sometime but only now found I own a copy that came with my Wacom tablet! Time to start playing with Corel Painter.
