Thank you both for your kind comments!
This pix were shot after some oil washes. The lighting conditions are pretty different, which makes the pix hard to compare.
I added an over all "filterwash" of burnt Sienna. Then I added a warm Grey and some white to filter sun exposed areas (roof top/ front) . For some deeper shadows I used black. The contrast is pretty harsh now, but the flat coat and some pigments will even that out. Then I did a drybrushing with the base colour Desert Yellow and some Buff.
I am not quite satisfied with the colour of the front glacis (between the flags) .. maybe I'll redo that (maybe the colour layer was not opaque enough and too much black is showing through? )

(sorry for the blurry pix)
again: comments very welcome!
best wishes
Steffen
