Lacking basic controls such as undo or revert to original.

This is a cool app. Can do a lot of interesting things. I would like to be able to import my own mask if possible. Thank you

I enjoy the heck out of this program. It gave me exactly the treatment I was looking for to render sketched graphic-novel style images. Works with all kinds of pics (i.e., real photos, cartoons, drawings, etc), and allows a ton of customizations within each filter, so you're bound to find a combination that works for you. Nice intuitive interface, simple to use, FAST rendering, and has never crashed once on me. Thanks for putting this out there, it's a great little program.

I have not been able to get this app to work. It quits unexpectedly and I can’t use a photograph to create the artwork around. Very disappointed in this purchase.
