Ouch.
Well, your fonts could use a lot of work. Download fonts at http://dafont.com or http://1001fonts.com and try a new variety and new positioning. You could get tons of brushes at http://deviantart.com by looking up Brushes or if you're looking for a specific type you could write the exact type and cross your fingers for the right outcome. It's far too basic to only have basic added 3 times on your signature and the border is far too thick. The colors seem to match it but that white thing isn't really following its flow. You could try adding a bit more to the background to allow Samus to blend in a bit more. Try making some more effects on it to make her look as if she truly is powerful.
Not a very good signature to be honest, obviously your first so it's acceptable but... If you want a better guide than what you probably used use this http://www.deviantart.com/#order=9&q=signature+tutorials and find a tutorial fit best for you.
Technically, no, because at any point we may decide to not post in this topic and completely ignore it being in the forums which in the long run would have created the reality of us "exiting the Rat's Wheel", I assume this is right.... right? :lol:
He is a 12 ft. Ogre with the teeth as massive as the Titanic before it hit its catastrophic end, no.. he was the true purpose of the Titanic's sinkage!
