No, but that's only because I'm dumb and getting old and don't know what instagram is.
Heh, that's cute. I wish I was that good at photoshop!
Here's the brush I used for the freehand stuff. I recently bought a bunch of them because they come in a variety pack of four and are dirt cheap for being under £5. I discovered that the quality can vary, and that the ferrule can break after a while but I drink coffee more expensive than that.

Twisting brushes? I'm not sure. That used to happen to me all the time, but not anymore I now realise. I'm not sure what I do different, but brushes just wear out even the best ones.
