update from workshop
I was setting up the column/flat north facade of the envelope to start with.... and also articulated the ground a bit ... were there is a descending staircase that gradually lead down towards the inside .... were I'm planing to test some water reflections tomorrow for the rendering... second image shows the articulation of the column and how the it touches the ground....WIP....

the bottom image is LOVELY!!
can't wait to see how they develop.
with the top image, maybe is worth raising the camera so there is not so much sky in background and not so much floor in foreground.
