Since I had done my first and second as a rather aggressive and defense poses, I decided to do something in the middle. I thought it would be a great chance to do something more scenic, and maybe even a Riptide crouching. It came out reasonably the way I wanted it, though due to the nature of the legs you can only compress them so much. Overall I got some great feedback and I am happy, which is the most important part.
I started off by building a square building, laying on it's side, so the Riptide would have something to stand on.
The finished model. It came out taller than a normal riptide, though only by a few inches.
Bonus picture. Three Crisis suits I hacked up their legs and arms to repose.
