for me its hard to tell because it looks like ur hands might be weighing your hair down so i can't really tell if there is a curls pattern and how big or smalls the curls might be...
How long is your NG?
ETA: looking at it again i *think* i see the beginning of a curl trying to happen. So that *might* eliminate 4b.
hmm...... ( looking back at it one more time.. lol)
