Well, there we are - a pair of feet. But what a lovely shot. And it almost makes them look - well, attractive - which, when sifting through the shots in this challenge is actually quite remarkable.
The white portion to the right of the scene is very distracting though and I would have removed it.
One light source are indeed very impressive studies. However, it is important to control the shadows. Your texture and lighting here are excellent. The only thing I would have done different is to have separeted the right foot enough to clear the stark shadow it leaves on the left. Bumping image from 5 to 6 on visual presentation.
High-contrast technique seems suitable for this challenge. This is a good example, where the subject has distinctive shapes which show up well in high-contrast, and where you might not really want to see all the details ...
