Speegs,
I can tell you that I had 2000 grafts in the same area you did and I am now 4months post op. Mine looked just about the same as yours at 13 weeks. the best growth for me is JUST NOW occurring. It was a bit discouraging when I would see other guys at 3 months with a lot more hair than I had, but I am feeling better all the time.
My hairs seem to be thin as well but they are progressing better than they were just 2 weeks ago. Some of us just start off a little slower than others. Smile and just sit back and let it happen. Believe me I know how you feel.
Aloha Russ
