Keizmos, you could try to shrink the Background, move the Avenger and Character closer together. The Avenger is stretched and looks awkward. For the Abstracts you could try some blue or white Glow.
Kurigauth, I liked the old RoS Signature much more than this one. I don't really like the too colourful Part with that good looking House on the Planet. Maybe try it with other Colours.
DarthBindo, .gif ....eeewww.
Bain.J, I like the Gaian Signature, but you should try too..uhm edit the Ships, so that they fit better into the Background like the Osiris in the first two Signatures.
