Doh, someone already posted that link! *blush*
I do shadows so many different ways... I can never decide what I like best. Sometimes I like to do my own shadow layer and distort it (I use PSE 5.0) and other times I like to just play with the settings... I am not consistent AT ALL in any of my shadow work.
One thing that surpises me in many LO's these days are how "exagerrated" some of the shadow work has become, especially in the very artistic style LOs... it's sort of hard for me to go there, but I admire how it looks...
