These look like hideous funhouse mirror faces. This is a great idea, but the execution is flawed. These are absolutely ridiculous looking - and look nothing at all like the sample on the item page. They look fine when flat, of course, but once they are put on, they are completely misshapen and look like a funhouse mirror. If you want a good laugh, then go ahead. But if you want a true version of your face, skip these.
I guess there is a slight possibility that changing the crop of the photo might make it somewhat better, but there is absolutely no guidance on how it should be cropped (other than the shape) so I feel like it would just be too hard to get it looking like a real face.
