On the left side, I see uncoordinated brushing/smudging/blur and it's only noticeable when observed for awhile. I noticed either the very edge of the image on the left side was transformed to actually fit the contents of the canvas or went unattended. The grunge-like brushing kind of distracts me n the right.
The contrast is great, however that in itself is in contrast to the title 'Darkly Dreaming'. Her hair seems to stand out more than anything, but that varies from person to person.
