wow, a classic japanese heian-period pic. those space around gives more freedom to the viewers' imagination. kinda reminds me of the murasaki shikibu, the first japanese novelist. perhaps you can add some japanese calligraphy which fills 3/4 of the space on the right to 'allow' her (that japanese lady) to express emotions. that way too enable viewers to understand her actions posed here.
overall, fantastic classic wallie. and it's going to my fav :D
