Shitty effect.. :P:P:P
Anyway I believe that the box in which the stock/render is placed should be wider ( as wide as the width of the signature. The att,def boxes should have the same width and height too. I like the background of the layer in which the effect is described. What else? I believe that all the layers ( except the one in which the render/stock is placed ) should have the same color and background. Anyway, nice try. :D
