Yoh and Anna

My favorite Shaman King couple! Anna there is supposed to be smiling but she looked weird when I was drawing her with a happy face so I changed it to her usual facial expression. Now that's more like Anna!
And one more thing, Anna and Yoh were supposed to be in a back-to-back position but I forgot to do it after I finished sketching Yoh.
That was my first time to draw Yoh but my third time to draw Anna. I can't understand why I had a hard time in drawing Anna, I usually suck in drawing guys.
