Help me identifying this fancy little thing

When I saw this book cover at my attention was immediately drawn to the B of Bones. I know this lettering is hand-drawn and not actually a font, but could anyone help me find some fonts with a B like that?

I've been trying to produce something like that but modifying Erato Light. If you want to take a look at it and give your opinion, click here.

Thanks in advance!


Font is called Rudolfo

It is actually a font, then? Thanks!
