Hello !
I saw your Mikasa incredible artwork and I choosed you to make real my idea :
Hanji on Pieck (like the attachment) fully nude and seeing each other in the eyes with a very focused and passionate look.
They have normal sized breasts (like your Mikasa artwork), natural and normal sized nails and triangle pubic shaved style (like the attachment).
Finally, keep your Mikasa artwork style because it is amazing !
