In my opinion the lines are a bit too thick, that is what I see..
Anyways I love this vector art from you Luna-chan since I love music as much as you do. I haven't watch the anime
yet, but I bet it's great isn't it? I love it so much Luna-chan it looks so sweet....
I can't really say any negative thing..except for the lines..but you did a wonderful job ^^
By the way...you get your vector art inspiration from music right? If you do..would you like to join us at Hope you'll join us ^^
