Flying Ghost or Cloud Witch in the Sky

I am not sure if this is a natural cloud formation that created the image of a flying witch of it this was done with photo shop.  It is a great picture of a ghost or cloud witch though.  Not something you would want to see on Halloween.

Halloween Witch’s flying in the sunset

I love the look of the two witch’s flying into the sunset.  I wonder how they did this picture.  It looks great.  The silhouette makes it look wonderful.   I wonder if they are flying off into the Halloween night.
