I like ur first two even though they look the same. They're not bad. Too simple though, maybe if you added more into them they would be decent sigs. Oh and you wrote grunge. These don't really seem grunge to me.
The background is good on the first two, with some shapes and lighting effects on top those would be good sigs.
