Instead of putting your own rating on what you think the sig is like in the title, how about making the title what it is?
Anyway, I really don't see anything great here. A psd that doesn't really look blended or anything. A background which is almost a solid color and a square with lowered opacity with your name on it.
Read tutorials, blend, learn to make better choice of colors, download some good brushes, then we'll see what happens.
