Made a few new sketches :D
They're a little faint in the pictures, but hopefully you get the gist of the drawings. The second one was a bit of trouble, as the heel would probably snap in real life, so there is a thin steel rod that goes through every curve in that heel, just a straight rod, if you get what I mean. If you look hard enough you might see it, but don't kill your eyes.
Feedback :D plzthx
edit: they're also a little skewed - done quite fast while it was still fresh in my head.
