It sort of looks like (to me) that some of those areas might be better served as grassy collection areas for chipping, rather thatn as bunkers. Actually...it kind of looks like some of those bunkers WERE infact cut out of previous collection areas...just my impression.
I also feel that, at least from this vantage point that things are a bit busy, with all of the up-font mounding and bunkers...but as JohnC says, there may in fact be "more than meets the eye" in terms of putting surface and run-up area than we can actually see here in this image.
