Hope you take what I'm about to wright has a positive thing, because I'm writing it in a positive mood
1st - Mate, you are trying to sell yourself here, the application is your 1st image to a guild where you know no one. I suggest you to take it into consideration and edit it

2nd - Though you didn't post the link to the armory I went to search you there, and I have some concerns about your gear... I know we all need to gear up at some point, and everything counts, but if you're DPS, having tank gear just because its purple its a bad idea. (not to mention PVP gear to do PVE)
3rd - You spent 71 points in the blood tree... that is... the word I'm looking for is...WRONG, and I can tell you why. 1st, since all the Death Knight trees can tank, using all 71 points in the blood, you're taking tank talents that you don't need. 2nd, in the 1st tiers of the other 2 trees there are great DPS talents like Vicious Strike, Virulence and Black Ice. This said, you're spec is wrong in every aspect of it!
4th - Blood DPS trees are DEEPLY dependent in gear, and, with your sepc and gear, I doubt you can even reach 1k DPS (minimum for heroic runs is 1500)
All said and done, you need to improve before you can raid, or even run heroics for all that matters...
Sorry, but from me you're a NO GO!
