From the Doctor Who tenth anniversary story - The Three Doctors. The Doctor has to help the Timelords when a black hole threatens to drain all of their power. But he cannot fight the scale of the menace alone. Summoning the last vestiges of their power the Timelords lift previous incarnations of the Doctor from their time streams and throw them together to help one another.
This was painted in 2010, but having just seen the special edition DVD sleeve art, I'm wondering if this piece was an influence? The reference material isn't surprising, but the composition is similar.
