What's the gray stuff on the foot?

It's a bandage... There's a damage on the statue, if you notice...

If you're trying to make it look like a real foot, to me it doesn't look like a bandage, it's just distracting IMHO....

Shoe demands a bit more work...u have to add a little more shine and glow to achieve a glass effect....

Author. I think that the original (European) version of this story has the stepsisters cutting off their toes and heels to make their feet fit!

the slipper needs to look more glossy to have the glass effect and the foot is a bit too flat. Nice try though

sources are not working ???

Thanks for the comments. I worked on the links - I think they work now (hopefully). I'm going to work on the shoe a little when I have a few minutes. Thanks for the advice.
