よろしく.
(*In my opinion, saying よろしくおねがいします would be better for the first time.)
はじぢめまして。. わたしはわニコールです。.
*Japanese has its own period and comma. (。and 、)
Good job! Please enjoy learning. I hope this was helpful.
よろしく.
はじめまして. わたし は ニコール です。
( "wa" as a particle, you write it は and pronounce it "wa" )
