Photoshop - Dramatic broken glass effect on Mike Tyson

This was the original image that i used. I got this image from http://mediagallery.usatoday.com/Mike+Tyson+through+the+years/G3524

I then used this broken glass picture and i was going to use these images in photo shop to make it look like Mike Tyson was looking through broken glass.





I used different things such as horizontally flipping the glass image to position it better, using the effect screen to make it transparent and then it started to come to shape. I then used the polygon lasso tool to weeve in and out of the hole in the glass so that i could make a mask to make it look like Mike Tyson was really looking through a broken part of glass.

I also used a grey texture layer in-between these two images to make the glass look a different colour and to help make it look like Mike Tyson was looking through glass.

This is the finalised image.
