Its too monochrome bro,
which kills it because it looks like the tag is well done. Try changing the monochrome with a bit more colour. The text is also hard to see.
There is one thing about your sigs that ruin them.Its the way that you overcontrast everything it works ok for black and white but with any colour you use it is way to overcontrasted and just looks like crap, your ruining your sigs man.
