Needs more color!!! It's too plain with just one color, and the right side is extremely empty D: Also, you might want to try different fonts too. Read some tuts and keep trying though!
To be honest, I think the blue suits this sig very well. As that shade of blue indicates a very cold and empty environment that a nobody would live in :3 The gap on the right kinda emphasizes this emptiness even more. If this sig had varying colors, it simply wouldn't have the same effect. I love it! 5/5
it needs some more variation in the blue colours so it doesnt look so bland and add some effects so if doesnt look so flat.
