Not really feeling the stacked and mixture of images. Having two images of Vegeta, then throwing in a Metal Kooler is not sticking to basic theme, which I believe is the best strategy in sig making. Also, having a BG (preferably textured with the brush tool) is another great way to realize numerous techniques in sig making.
How do you think Sakuma made the sig your using? Brushing with layer styles and layer filters.
This sig is basically three stacked images, opacity varying. 1/10
