I humbly present my design for a Lego Balloon Dog. I have not yet seen such a design before, but have wanted to build one for a long while ever since I came across the official minifig sized version that Lego produces.
This design uses a number of interesting SNOT techniques on the inner side of each part, ball joints for the connection and looks amazing on a desk or shelf. The scale is fairly large, but that's what makes it amazing :)
This design was very challenging to achieve given that the necessary pieces required for a consistent color scheme were limited, but that is something that can be refined and redesigned, and the structure strengthened and streamlined should this move to the next phase.
