The hair indicates brisket and arm pit location. The white hair is in the crease just behind the shoulder. The dark tipped hair is located on the lower portion of the brisket directly below the crease. This is consistant with the fat on the shaft. If you had little to no blood it was a superficial hit.

If you hit high enough to clear the inner portion of the rib cage where it connects at the brisket there is a slight possibility that you could possibly have hit the pyloric (sp) artery. This is a slow bleeder. However if you did, it wouldn't be consistant with the fat that you say is on the shaft.

By only looking at the photo's you've supplied, I'd say it was a superficial hit. The deer will survive.
