@Gopher I adore how people like you can make few colored brush strokes and create almost complete background, I feel so envious! And I know that you're just testing waters with the colors (wink, wink xD), before going ham on it, but in this picture they all look very wraithy/ghostly and less wattery, I would advise to add some moisture to give proper vibe to it! Keep up the good work!
I am so sorry to ghost out on this challange for the week, cause its time for exams, and Im barely prepared!
