Are any of these good enough for my sig?

I made these collages from a paint program *lol*. I'm currently using a laptop and that's the best it's got. These are actually just about the first graphic image thingies (*lol*) I've ever made. Would these look okay on my sig, or are they just junky and wouldn't look good?
