Craft Edge

I am new to SCAL, and am loving it so far. I am hoping to create an image to cut with vinyl and etch on glass with this: http://www.pwoc.org/Resources/Resources ... _print.jpg
I am having a hard time getting a nice edge and getting rid of a bunch of the bits and pieces that are left behind. I just need it to be able to etch nice. Can someone help me convert it? Thanks so much!

Can anybody help with this picture? Or help me to figure out how to get a clean cut for etching onto a mirror? Thanks so much. It is a Christian Image... in case you are afraid to open. I just cut some more wonderful items through SCAL, wow, it is awesome!
