Animal tracks bangle

My animal tracks and bird tracks silver bracelets have always been popular so I thought I'd try using tracks on an aluminum bangle.

I dyed the background a new color - it is called olive - but actually came out grey - but I quite like the smoky color effect. It's not very different from the aluminum color itself but does add a little something.  I know, I've been using a lot of color in my aluminum, so this one is a little different as it's just greys and black, but I like the subtle grey with the strong black. What do you think?  

And can you identify the animal tracks?  Go on, give it a go......

The perfect bangle for a hike in the woods.....
