For scaping were used 41 lb of live rock "Pukani", which have previously been cured during 1 month in a container with little light and a couple of small pumps to circulation:
I've also used 13 lb of rock (mostly Deepwater) I had in the sump of Iwagumi ... in total, I used about 55 lb of rock to create the Bommie.
And after a whole morning shaping the structure, this is the result today (put it in HD):

The water flow is critical in this new project, because not only want to make a natural scaping but also get some forms of growth the most natural possible in the corals... for this reason, I located the two pumps faced to get a great water turbulence on top of bommie, where I will place the most demanding species, as acroporas humilis, Pocilloporids, etc.
