First, nice job.
I also live on a small island in the San Juans and have discovered that a two year old buck (and mature doe) will yield about 30-35 pounds of meat, a three year old hits the mid forties and a four year old I got last year provided 54 pounds of meat. If you are meat hunting, let the bucks grow up (not bagging on you Oneshot). Looks like yours was maybe a three year old, we have a tall spike just like that that was smaller last year (one antler bends forward, the other to the back so he is recognizeable).
They are good eating though.....
The bigger the island, the bigger the deer tend to be as well.
