Your lilies are beautifully crafted in their simple strokes but leave a vibrant touch to the dramatic scene in this piece. The illusion of light on the water as well as shadow lines from the top are my main reasons in why i state that this is a dramatic scene, one that is almost towards a romantic view with your hushed hues of pink. The leaves, i feel, deserve a stronger edge and the water a bit less green in order to pronounce the pigment of said leaves. While i can find that your main focus in this is your four lilies but the leaves can be just as singularly important. Your colors, aside from my opinions voiced earlier, are just about as close to spot on that i can find. This is very lovely and captivates the eyes making it hard for me to focus on individual parts but great for letting me take it all in at one time. Over all this is just simply splendid and, as its tittle expresses, tranquil. With the small hint of movement and rolling from the water it allows the piece a feel of calm, care-free relaxation.
