Mikoto Urabe and Aika Hayakawa from the anime Nazo no Kanojo X (Mysterious Girlfriend X)
Wow this one seemed to take forever... Even though the I have recently been coloring the whole page (9x12) this one seemed to take ages! It took me 5 days to finish, working on it for 1-2 hours a day.
I used copic markers to do the hair accents for both Urabe and Hayakawa. I goofed and grabbed a blue marker that had a little bit of purple in it when doing Urabe's hair. I wanted to use an ultramarine blue or something of that nature haha.
