Hi Lim Zhen,
I think, right after takeoff, with full load, a 7 degrees pitch is normal, and it should decrease to 2..3 at the end of the trip. I remember when travelled on a 747 to Korea, I felt that I see upward, when looking into the nose, but I was not sure in my feelings. Then I was walking on the deck, and I could feel this too a little.
