Flower and Bird collage

Well, this collage is about finished, although I do think it needs something more, and I'm not sure what. The background has many layers, starting with buff titanium gesso, quinacridone nickel azo gold acrylic paint and quinacridone crimson. At this point I felt it was too bright, and I also wanted some texture, so I collaged on some natural colored japanese tissue paper, which I scrunched first. This was dry brushed with titanium white, and a bit of raw umber. The bird (from the same collage/ wrapping paper sheet as my last bird collage) and flower (The Vintage Workshop) were added. Shadows and corner shading were done with a thinned wash of raw umber.
