I built the latest Sandrock Custom kit, making some minor proportion adjustments and keeping a production notebook.

The modifications are relatively simple, so please check the notebook for details if you're interested! (CV: Shakti)
While retaining the HG's strengths—a powerful physique different from the long legs and small face of the original design and the MG version—I tried to eliminate the slightly stubby appearance, though it might be hard to tell!

I only did relatively simple modifications, and the difference is hard to see, but I got a sense of self-satisfaction (lol).
Modifying the inside of the side skirts and painting the inside of the armor are easy and improve the overall finish, so they're great!
