I have completed snapfit of the main body, this kit really looks awesome! However I cannot manage to get the exact same pose like the one in the boxart, the are a few parts that hinder the articulation. I think Bandai should have base this kit on MG RX-78 Origin frame, and not the 2.0 inner frame. The MG Origin RX78 has much better articulations.
Anyway, I’m planning to modify the parts that block the articulations, I marked them in my pictures. Notice I have to removed the ankle armor to achieve the bend on the lower right leg.
