It has a peaceful sense to it, aided by the cool coloring with red touches here and there, the soft shadows and the focus around the eyes and subtle blur. The head tilt gives it a little movement and dinamic feel, without disrupting the quiet overall aura.
Composition-wise the dominance of the head gives a feeling of closeness and confidence, even though it might be a little too dominant. in the whole picture.
I probably would've liked a warmer light a little better, but then again it might just ruin the tranquil feeling of the piece.
But the thing I like the most about it is the focus around the eyes, with that unique olive-green coloring and the intensely contemplative expression the have. Lovely. Cheers.
