Looks a lot better than your last signature.
But you still have lots to go.
The text doesn't looks so hot. Go check dafont.com for better fonts.
Also, a small tip. Even though it doesn't seem like much, adding some curves to your image can actually make
10 times better. But overall it looks better than your previous works.
EDIT: Look at what just adding some curves does to your signature.
All I did was add curves to your layer.
