Hmmm, think to put your contact in your background. He didnt' fell from the sky (well, actually he could, but it must be a pretty good story).
Now, critical strike, ok, cool stuff ; then I'm wondering about your attribute boosts : is it the power which you must activate and which grants you a bonus equal to the success of the test, or is it the power which improves permanently your attributes ?
If it's the second answer, then I think it's the wrong name, and you shall drop the body boost, and replace it either with 3 lvl of the true attribute boost, or with 3 lvl of enhanced perception (which will help you be VERY perceptive, plus it works with assenssing too).
