I use paint shop pro and work and understand layers, same with photoshop but there are more brushes with that program so it can be a bit daunting when you first start up.
go and join the WETCANVAS forum navigate to digital art.
In the meantime I will send you a link to a work in progress of mine using digital software if you let me have your email address via Private message.
