A very promising outlay Pedro,
A few observations that catch my eye are the open toolbox on the Famo. As the Famo is obviously in transit, and has only stopped to fill a few jerry cans, that toolbox would not be there. Tools like that would only be opened when in use.
The newspaper seller is a nice touch, but I would place him more to the front of the vehicle, as if he's trying to attract the attention from the crew in the vehicle, who have obviously nothing much to do. Where he is now, he looks to be holding up the paper to the backs of the soldiers filling the jerry cans.
The locker door on the left is open. Why? there is again no reason for this to be open, as there is no obvious maintanance or repair work carried out.
A suggestion would be to get one or two soldiers to do some quick maintanance at the engine, like checking oil or water, or perhaps having a look at a wheel, checking out a bearing or such. These are the sort of tasks that would be done during a stop, and would add a bit of action around the scene.
Good start so far Pedro, looking forward to more progress pictures.
Cheers
Henk
