Interesting picture. It is normal for control surfaces to droop when hydraulic pressure is off. Control surfaces are balanced, but usually never dead nuts so to speak. For instance, MD11 elevators are balanced tail heavy. It could be a case where the elevator shown is balanced nose heavy, but I wouldn't think that is the case. Maybe they just have the elevator locked in an up position for MTC?

The question has already been answered. With no hydro on, the elevators will go where ever the wind blows them! Its not uncommon to see all of them down, all of them up, one down, one up, you name it, it really just depends!

I really dont know what the general question is here, but I cant imagine there to be any hydrolic pressure in this photo. The engines are removed and the plane is not connected to an external generator or pump. And if you look closely at the gearbay doors, you will see that they are hanging from their sockets.
I dont have any inside information on the status of this plane, and the photo was not shot from airside terrain.

With an a/c in that state I would imagine all the PCU's have been removed.
I'm suprised no-one has noticed both hi-speed ailerons are down and the RH Lo-speed aileron is up as well. The position of these controls wil depend on how they are balanced and what influence the wind has.
The postion of the LG doors means nothing as thay may have been dropped by maintenance.
