Everything in the scene is either has a shader or textures that came with the model. For lighting, I am using an HDR of the Pixar Atrium, a key light pointed at the violin and a light for the candle. Overall, I'm pretty happy with the color scheme. I really like how the dark maroon drapery helps bring the violin out. I might change to the pedal color on the tulips to probably a saturated red and reassess the shader on the vase. I will say, however, the overall brightness of the images seems a little dark. I think it's from how I am converting the original tif file to a png.
