Sorry it's been a while. I am ludicrously bad at this commenting malarkey.
Nice piece. Definitely like the foregrounding on the hand, and the clothes texturing is splendid. The sea green material on the left seems a little out of place in the colour scheme - is that intentional?
Can't even see where it was attacked by the dog - an accident which sounds like it could well have proved fatal for any artwork. Kudos to your photoshopping, perhaps
the green is actually a bandana tucked into the waist of the revolutionary, green being an important colour within the arabic world, more so with muslims and such. It was mainly added to reinforce the effect, as the piece features all the typical palestinian symbols so it seemed right to put in that object.
the attack was more of an act of sabotage (i think my dog is a Mossad agent)- paint was knocked onto the top of the work by the dog, so i had to blur and erase a fair bit of the background colour to repair it.
As usual, it's amazing. I like the perspective and how it's only focused to a certain degree not only on the page but the image as well. (I hope that makes sense) This may sound odd but you should be used to me by now, (heh) but I really like the leader's hands. They came out so well... perfect!
