i would have increased the contrast of the arrow as well. it's difficult to see and that way it's difficult to appreciate your idea and purpose.
Right now the part you actually wanna see is the boy who is completely out of focus.
oh, i haven't seen that this is actually from you.
Well, in that case - you achieved your purpose. I saw that arrow, but didn't thought of an arrow at first. I thought it is dirt on the bottom and that's not interesting. then i thought - funny, that dirt looks like a foot print of a chicken - but a little big for the boys head. at that point i already clicked away and to be honest - i didn't see that this is supposed to be an arrow until i read in the comments that it is an arrow.
