For those who are curious about how I work, here are some screenshots from the progress steps of the Moonlit Dream, found over here -> [link]
As you see, in this painting I started with thick brush strokes here and there (sharp-edged round brush) just to catch the feeling and mood of the concept, and then I kept on refining things and adding details to the points of interest, until I come up with a satisfying result. In the end I decided to place some oranges for contrast, in order to break the monotonousness and make the image look a bit more interesting. It's like the cherry on top of the cake
I hope it will help somehow...
