Editing In Photoshop

I urhm, acquired a copy of Photoshop CS5 and have been playing around with my raw files. There is so much to Photoshop that I'll never fully grasp it. So far I've managed to do this... sort of.



The photo on the left is untouched, except for the cropping. The photo on the right has been touched up a bit. I attempted to remove the shine on Stamatia's face. I also adjusted the exposure a little.
