I finally remembered to check this!

While looking through my inbox, I stumbled upon the link you sent me and recalled being unable to listen before. Well, I finally did! It's critique time:

Firstly, don't use a strained voice. You could easily get a better - and especially more distinct - version of this sound if you were to pull back your vocal chords. See, you can either over-tighten your vocal chords (as you're doing now), or you can pull back until they're barely touching, an exaggerated version of which is the sound made by The Grudge. This technique will give threshold for clearer diction and a more prominent sound. Of course, you want to keep that incomprehensible, rambling country drawl, but voice acting requires unnatural diction and clarity - so you'll need to overdo it a bit.

Secondly, you need a little more vocal fluctuation - just a smidgen. While, again, you're character is meant to be monotonous, too much monotony will simply make him uninteresting. As I said, voice acting requires you to overdo a lot of things.

Overall, though, it's not terrible. I've certainly heard much worse. I'll give you the 7 and 4.
