Album cover

Here is the album cover that we are going to edit for our first piece.
I did the photos of myself in the style of Paul McCartney's on the 3rd row.
These were the photos that I sent to a member of the group, as he assigned himself to edit the photographs. As I have never edited or created any work such as this before, and I do not have any of the software and do not feel confident in using it at the moment, I am going to research some styles and ideas for the other piece.
