Made in Photoshop CS5

Pretty great.
The basic-ness works good.

Looks nice, though the stomach block seems a tad out of place.

This is great.
It looks so much like a tori I could have mistaken it as a screenshot if it weren't for the colors used in this, which compliments each other perfectly.

This is simply wonderful.
I love how it looks like the chest is rotated to the right a bit, as is the lumbar.
The layers of transparency were done very nicely as well.

Would love to see this in oil paint; As it already fits that criteria.

Don't know about the head but overall is a pretty decent job.
