Miundel's dark side

Waah, I wanted to draw Miundel's dark side since a long time. At first I just wanted to practise wings with my brush, but as Myu spreads his wings when he's dark, it ended like this. ^^
Well, Myu is half devil, half angel, and when he is really cross or something disturb him (strong feelings in fact make him explode), the devil side come out! So he become berserk, the only way to calm him is too hit him or well... kiss him. (this solution doesn't work with everybody thought ^_^, )
And in this form he's like a beast and has a dreaful aura, really frightening.... *shivers*
Well, he spread his wings to "intimidate" the person in front of him (a devil's attitude).
I will do another pics of his dark side. ^^
(in fact, Myu is a 70/30, this mean he is 70% angel and 30% devil, but it doesn't count when he's berserk)
