I really like this painting mainly for the color scheme and the arrangement of the flowers. The reds and whites look really nice together and remind me of Alice in Wonderland when the Queen ordered Alice to paint the roses red. With the arrangement, I like that the flowers are not directly facing the viewer, but are stretching in opposite directions from one another. There is a lot more angles to play with.
I also really like the lighting and dark shadows in the background. The focus and light is primarily on the flowers, which makes them pop a lot more. You can see the table that the flower pot is placed on, but even that is very dimly lite and shadowed.
