OK, let's take a looksie.

"Name: Selí̱ni̱ Aimafo̱tiá" Is there a reason her name has been liberally machine-gunned with accented characters?

"It's core is the cast skin of a coral snake" No. Coral Snakes are not a magical creature, so having the skin of one as a wand core will not work.

"Pretrained at potions an rumored to be a Parselmouth the latter yet revealed" No. Just no. Parseltongue is a defining mark of a Dark Wizard and I'd rather not go there. Also, given the amount of dangerous stuff involved in Potion making I find it unlikely that any parent would attempt to teach it to their child.
