I think its interesting that the little boy is strong and standing and in the dark. The old woman is old and helpless and looking into the light. Could be taken either as uplifting or dark - but the movement of the colors and the intricacies of the brush strokes makes this piece so much fun just to look at!
Initially when I saw this I thought it was an interesting more realistic take on 'Scream' she seems to be in agony and the back drop is similar. On closer inspection I see the composition of the piece is much more thought out. Her face and positioning lead you to her and the uncomfortable angle help you empathise with her. The curve of the earth as if there is so much beyond this woman and the tranquillity of the boy in the background with the balloon makes for a stark contrast. Don't even start me on the colours. Excellent piece.
