Now I may be being unobservant here but for the life of me I cant spot Waldo. Got a feeling that when i look at the description after the competition that you are either going to have been teasing us and there is no waldo or else he is blindingly obvious and I will feel slightly stupid for not having spotted him. like the 'almost but not quite centred' composition
The arch and the doors are interesing. I like how you handled the foreground shadowing. Beyond the bench and tree the details are too pixelated to be certain, but I think there is some sort of post, then a door and Waldo is a silouette behind the door.
