As far as conceptual ideas go, I know that I want to create a body of about five images that make use of the human figure. But I don't want to constrain myself necessarily by creating a cohesive "style", because I want to explore color palettes and drawing styles.
For tools I have at my disposal, there are many photoshop forums and tutorials available online, graphics magazines, the photoshop magazine, art communities, and digital art books are going to be very useful.
