Younger Nurarihyon Lineart

My first lineart/vector ever!!!!
Spent about 6-8 hours on it, I hope it paid off! I'd appreciate a little constructive criticism on this, l couldn't find any good tutorials on how to do lineart/vector with PS Elements 6, so I just followed my instincts.
I'm going to keep practicing though until I get all the lines straight. ><

Character is the forever awesome Nurarihyon from Nurarihyon no Mago. <3

Original panel was taken from Chapter 150

Please color it if you want to!!! And let me know if you do so I can see it!
