step 1 of 11
First, i selected as much avatars as possible.
step 2 of 11
Masked all avatars, and moved them close together. Also did some polishing up, to make them match better.
step 3 of 11
The front row needed something to sit on.
step 4 of 11
Created a new background by using a large dry brush, using different layers in mode 'overlay'.

Now with text, image and barcode. Also added another avatar (scaled up a bit, and added some grain to hide the resize artifacts).

step 11 of 11
Created background by filling a layer with grain and aplying a motion blur on it.
