Some nice techniques. This was a category that called for some action in the MOC, too, and you've got it. Those factors, combined with the scale and obvious time involved get ya over that line for me...score of 4.
The build was really nice with some fun action! I think "cleaning it up" a bit (tiles over studs maybe) would have made this one of the top mocs in this category. Teetering between a three and four here... (thinking...) yeah, you squeeked out a 4 points on this one. ~Chris.
