Colors are great...there is a lot going on there...but it will probably be less distracting once they are actually printed...I would probably loose the barbwire chain link
I would say get rid of the gradients in the blades & the 'in memory of' circles. Also, simplify the blades so that they are more of a graphic element and not just decoration; two layers of blades is too much. Definitely get rid of the paintbrush element that is ghosted over the top of the fencing, you already have the paint splatter at the bottom of the design depicting a 'grunge' or 'distressed' look. Less is always more.
