Quite like how this one looks, contrast between black and red is nice and looks good. The deep oranges and reds connote blood and make it look like a horror picture.

Fuzy kind of effect which i guess makes the viewer want to be able to focus on the image more, i think it looks more frustrating then anything else
Another subtle grainy effect, i was hoping to give it a kind of edge that would be sinister but it just looks like the photos been sewn together.
This has a subtle ripple in the middle that makes that little more abstract, the texture is also quite subtle and gives a nice effect that shows everything isnt normal. However it isnt real enough, i want viewers to think, crap, this could happen, zombies could be real.
Started to play with how id like images to look in my idents. The above image has a collage look to it, although i do like this sort of style it wouldnt fit in with the tone of voice of my work.
