Magazine Advert Editing Update

This is what I have done for my magazine advert so far, which is the background and the masks in the broken glass, as well as part of the title.
The hardest part of editing so far has been creating a hole in the broken glass foreground in order to see the masks in the background, this is because I had to use a polygon tool in order to erase the black foreground which took a lot of time, effort and accuracy in order to do right and still preserve the good quality of the broken glass.
What I like so far is the way the two masks are portrayed behind the broken glass with the shadow effects which make them appear sinister.
