Nebula

 The colour of the artwork takes you into those deep blue tones and times of life, when slowly from the dark some things start getting lighter. 

The lighter fades surrounding the darker tones of the piece. It combines to form a very interesting composition together. The sharper lines, the blue fades, and the grim darkness all of it acts as a point of focus. 

When you look at it as a whole, the painting looks balanced, flowy and beautiful.
