Unfortunately, unless you have the older version of SCAL or MTC and the older firmware from the cricut (not sure about that last part) you can't cut your own files with the cricut. The only thing I've seen some do is use Design Studio (which is also pretty much defunct) and a lot of shapes from cartridges to try to duplicate the image. I'm not sure if you can do that in cricut craft room. The basic idea is to take circles, ovals, squares, triangles, etc and sort of fill in the shape and then weld. It would be a pretty big job, I think.
