Bassman:
I love the body of your bull, very nicely done!
About moustaches, yes, they are not easy to be done, yours look fine.
I made mine two ways, look at my death and fire sorcerer:

Death sorcerer:
I stuck to sausages of gs and detailed with a sharped knife, they looked a bit messy, then twisted them with my hand and turned upside. When they were half-hardened I retouched details.
Fire sorcerer:
my big problem was the moustache pointing outside, I decided to go for a pin inside! Then I shaped the moustache with a sharpened tool, to get this final result!
Hope to be helpfull,
Bassman
