Obsessive, Compulsive, Repetitive

CRITIQUE PLEASE!!

Art project, we were given the title "obsessive, compulsive, repetitive."
I started by looking into mental health, focussed on depression and self harm, this was when I found out that a TINY percentage of horses self harm - go on, google it! Anyway... The mask represents hiding. Just a basic manip to get me back into the swing of things!

Background: [link]

Other:
