I'm fortunate to make the majority of my living with photoshop. Every now and again I get to have fun with it. I can hunt up some examples if you are interested. An online example is here: http://www.childrens-museum.net/
That site was mostly photoshop with 3d elements. I'll also do magazine covers for my friends kids, I don't sell them (copyright infringment) but will mock them up and give them as birthday presents.
