Lots of fun!

Great application, and extremely fun! Only problem I have is if there is a "shiny" spot anywhere on image to be "sketched" it creates a black spot. For example - I had a bunch of pix of 1st graders for a teachers gift. After importing into PhotoSketcher it looked like they had dark spots on their teeth where there may have been a shine. Had to retouch the originals to eliminate shiney spots before bringing them into sketch mode.
This app is really fun, but not without issues.
