Avatar alone: 9/10, what's with the skulls? Anyway it makes you look more scary.
As Hani said, it's Skulduggery Pleasant, a series of Novels by Derek Landy. The reason I have the "skulls" (his face) is because lets be honest, he's over 100 years old, is the only living skeleton in the world that feels pain as if he was living. Uses the elements (fire, water, air and earth) as if they were his toys. He is also cocky, egotistical, eccentric, and has quite a dry sense of humor.
Then not to mention I got the p-brained idea to base a name off of how Derek chose the names of his characters in the book. Thus chose Pragmatic Wisdom, it fits perfectly well with my gaming style even if it sucks, because I know there is still room for improvement which is why I have my quote as it is on my signature.
Hope this has helped open your mind, yes? Also, I suggest you read Skulduggery Pleasant, it's an awesome novel series that I find very few not liking it after I've introduced them to Derek's legendary writing skills. Also has a kick arse girl who named herself Valkyrie Cain (who is 12yo at the start of the series).
Anyways, time to rate Hani I guess
Avatar Alone: 7/10 - Head isn't centered

but I guess it's to avoid the overly large text needed?
Avatar In Relevance To The Name: 10/10 - You used your name in it of course, just need to make it all lower case now

Avatar In Theme With The Sig: 7/10 - Not completely relative seeing as the text on your Avvy isn't like it is on your sig.
Overall: 9/10 - Works well together on the post, so can't really fault it.
