hello khatmorg, You really made a much better "defender" than lego. congratulation! The proportions and the interior flow together in harmony. I feel motivated to start my own approach. Bit I would really need some "development aid". Problem No.1: I still do not come along with the download thing. is there another creative way to communicate about the fundamental technics used inside ? I am totally new in the forum, that's why. happy day!
