1000 grafts is not enough for coverage, let alone density. It's going to look pluggy, and see through.
NW2 2000-2500
graft count isn't indicative of actual coverage. The hair thickness and amount of multi haired grafts will determine the density and coverage. 2000-2500 seems excessive for a NW2. From what I have seen it is approx 1500 for NW2's so your numbers seem pretty inflated.
