Drawing to a target is unconstitutional. NC-4 is particularly suspect.
What do you mean "a target?" You mean drawing to create maj-min districts intentionally? I don't think there's any other map on here that has at least 3.
You can not assign persons to voting districts based on race.
It appears that you had a target (i.e. we need more black people in this district). You did not establish the three prongs of the Gingles test, Your NC-4 is particularly problematic in the way you linked Durham and eastern Raleigh.
NC-9 you would have to show that minorities vote cohesively.
Also Republican members of the panel would likely vote against your map because of NC-7.
Isn't assigning people to a district based on race required to create VRA-mandated maj-min districts? Regardless, fair point. I think NC-4 failed Gingles, but otherwise the others come across as fair to me.
