Note Dragons - Sharp, Basilisks' Crown

Uploading my newest Note, and I just loved it!

Again, I had to look for the correct translation (this is called "diesis" in my language), so if I made any mistake just tell me
So, it wasn't easy to find the right design for this shape, and it was initially snake themed. After some hours, I thought it really was kinda boring, and added the details on the heads, and so the "basilisk/cockatrice" idea came up in my mind.
I know, I know, the basilisk and the cockatrice can be seen as two different creatures, but they were initially the same beast, a chicken/snake dragon. Or so I know, so feel free to correct me ù.ù'
Now, I have a couple of sketches left, but I'm really running low on ideas/notes/symbols. If you like this serie, would you like to make a suggestion? It really would help!
Or, if you didn't really enjoy it, what would you prefer to see?

Coloured with pencils, with white gel pen details on the eyes and metallic brown pen on the background. Lineart made with black pen (again!).
