Abaddon - God of Nightmares

I made this boy today. I sketched the outline out and then scanned it in, coloring him in psp7.
This is Abaddon, god of nightmares. His parents are Chhaya, goddess of the night and Tynan god of fear. He is a strong unicorn, able to fly around to the sleeping unicorns and envokes their darkest fears. He can trap mortals in nightmares until the sun rises. He has the power to create what is known as a Deep Nightmare in which the pain afflicted in a nightmare physically happens to the unicorn (like if they get cut in their nightmare, their real body will be cut and start bleeding). However, he cannot make anyone die during the nightmares, and his powers are completely useless against gods. He cannot cause immortals level 5 and higher to have a Deep Nightmare. He doesn't talk unless it is absolutely necessary for him to. Abaddon prefers the dark and never leaves his father's cave during the day, feeling sensitive to the sun. He doesn't really care about either of his parents and prefers to be alone most of the time, though there are some times when he will just be near them, sometimes craving another's presence.
