Please check #72 #73 and #74 .
I update based in your last pic and shadows as u requested. A variation from box to dot. no sense for the box, the dot looks like same dot for (i) or can be a variation for a magnify like an icon for the search (marketing).
Thanks for your pic. Eso ayuda mucho.
The # 21 and # 36 ... reflect more what we want, what identifies us, what we are .... you have to make some adjustments to the designs and sizes, which I expect soon ... very good work in general ... thanks to all for their proposals.
