Well, I think it is awesome! Love these templates and am dying to try them out! Please make a collection of them if you can. One way to get a curved edge is to add a plain white square frame with a rounded inner edge and pull it so it is forward and ahead of all the other images, making a soft edge based on all the images in the collage. The other is to do it at the back and have a background image that would form the curved edge which would be made from just the one image. For a blurred edge use a frame with a translucent edge rather than a solid edge. Hope that makes sense!

COOL template!!!!
