Here's my interpretation: The water waves at its feet shows that there's still a ground, and gravity.
They're in space, but can't even wander freely after all these years bound on earth...
Their wing are broken, holding their shoulder in pain.
They can't fly either. The stars are just specks of hope in the general emptiness. Specks of hope, that are far, far away. Their warmth and light will both seem so insignificant despite the gigantic size of the orbs that behold this power...
But thats just what I thought seeing your work :) I love your art! :D it's really tought-provoking :)
