Not sure if it's all that perceptible, but w/ this image, I tried some subtle photoshop tricks I learned to give Haley some 3-Dimensionality, depth to the image

I took 2 years or so of 3-D animation where I learned tricks to give the impression of depth, even in a two dimensional image. It has to do w/ line thickness, contrast, lighting, blurring, layering....in every image I post, I think about where I want the viewer to look when viewing an image, then work my way from there....
