It takes 2 to dance the tango, just as you can see in the energies depicted in the painting.
Both energies are very deeply connected with each other, almost as if they have the intention to come into one energy. Tango is a dance you dance for the partner you're with, and their hearts are always close to each other. (This is one of the basics of tango dance, and also the reason why this painting gets it's place in the my art collection called 'hearts').
You can define the masculine energy and the feminine energy.
The style of the painting, is my signature painting technique, I've been working on since 10 years now. I use a very energetic abstract calligraphy brushstrokes, to und up filling my figures with colorful patters (oilpastels, and oil painting).
