Dude, you have to shrink it down. It's goddamn HUGE! It took a whole two minutes to load. Take the picture, put it in photo editer or something, and shrink it down to something smaller. Maybe 6 x 3 inches, or 5 x 2. But you have to shrink it. Also, the blending isn't that great in the sig itself. And when you're cutting an image, zoom in really close and use a small soft-edge brush, (the one that looks kind of like an airbrush). But, overall, a pretty damn good sig for a first-timer.
I have three different rating systems. 1. If you have 1-10 sigs 2. 10-30 sigs 3. 30+ sigs.
I am obviously going to rate you with the beginner system.
Rating: 7/10
P.S. Just check out some other sigs on the forum. Get some ideas, and incorporate them into your own thoughts.
