The following position appears during last Nijmegen Open at the 7th round
Antony Alavoine - Arnoud de Greef
Position after 34.48x37

Black to play
Previously in the game Black got a winning position but after a weak black move white reached the following position with some compensations for the man down.
My question is the following: is the position still a winning one for black?
My first searchs with Damy told me that the position may be a drawing position but I am not sure at all!
Can you help me?
