I absolutely love this.

Upon viewing, my gaze is instantly drawn to the fiery red hot, intensely infernal eyes the subject has. Slowly expanding from this position, I immediately notice the fresh bloodstains along the charcoal colored fur in an expanding view scope. The expression... can it be declared as demonic? Violently lustful? Is there any indication of evil or malevolence? I wonder if this character's battle has just begun, or is nearing it's end? You describe your character as insane. Is this a merit originally present in the artist, simply flowing onto the canvas? Perhaps this a glimpse into the mind of the creator of this piece?
