I hit 3, one at 70mph, in a 95 grand prix. The hood was a little worse than yours, flattened down slightly conforming to the chassis underneath. The hood was pressed down about 20 inches across by about 7 inches. The driver's side headlamp assembly was also sunk down about an inch. There was a very small dent in the roof where its head must have impacted as it flipped over the car.
I was travelling about 85mph when I saw the deer. I hit the brakes, realized if I kept them in the bumper/hood would be so low as to allow it to go unimpeded through the windshield, so I slammed the gas immediately. I'm very glad I did that as I'm sure it kept the damage to a minimum. I hit 2 more small deer within a mile of that stretch inside of 2 weeks. Neither of those did any damage.
