Hopefully constructive criticism is ok just two things
one
it may just be me but it looks like your computer is struggling to render and record at the same time as im noticing a rather low frame rate while watching. Simply put you should probably lower the quality settings down a tad. No one would truly care about the graphics your games running at if your providing good content.
two
An hour seems rather long for YouTube video's maybe try cutting down to a max for 10-20 mins per video. not only will you be able to upload far quicker but it will allow you to variate your games your recording rather than doing a solid hour on one game.
But other than that nice first attempt dude =]
i like your voice, it's interesting, but, i think it'd be more entertaining to watch a different game for both entertainment + frame rate purposes, since dark souls is a very 'defeat this to progress' game rather than creative where you can do what you want.
eh, but, that may just be me
