When I'm feeling Blue

I've completed my first ever diptych. A large one at that. Total 40 inches by 60 inches. This is a mixed media piece as I used tissue paper initially to lay down some texture. I'm not sure if I should call it 'Mixed Media' or 'Acrylic and Tissue Paper'. They work together or separately... hopefully they will be bought by the same client and he can decide how far apart or close he wants them.
