Today Shaun Evaristo, an American choreographer work creates routines for Taeyang and Big Bang, posted a picture of Big Bang in the studio, via his tumlbr.
Not 100% sure, but from the picture we seem to be able to see Taeyang, G-Dragon (in the fur hat) and a little bit of Daesung's leg (on the left side).
