Acrylics. The idea was that the front is more springish and the back is autumnish. Thus the front leaves are green, the sky is lighter and the grass is greenish-blue. The back leaves are red, the sky is darker and the grass begins to dry.I enjoyed the proccess, but I learned that I really should get new brushes.P.S. It's really a proccess of developing my style. I am trying to get my style more "me" - I like details (maybe doesn't show in this one but still) but I also like to have a free hand (like her hair=leaves). In addition I tryed to make it look more like classic children illustration by making it more 2D-ish. Hope you like.
