Human Anatomy Feet

I discovered i needed to sculpt in a bit of detail on the feet of the mesh. I actually found this part really hard and to be able to get an alright shape for the toes i had to use a range of brushes and slowly build up the form. I'm not completely happy with the results because on the front profile view it doesn't look correct but on a few other different profiles i thought they looked good. I looked online for some image references to base my sculpt on and give me a general idea of the shapes of the foot. Here is my final result of the foot for the human anatomy sculpt.
