Simple word, this kit is awesome. Actually this is my first time to build Real Grade kit from Bandai. My impression is it's almost similar with High Grade but more complex, not to complex like Master Grade.
The details of this kit are super, beyond the details of the Master Grade I can say. When it's not yet panel lining, it looks standard, but after panel lining, this kit is super super great. I really love it!.
The colors are great. The white, the dark navy, the yellow, the color separation, everything looks great. I love the tone of the color. Not too bright, not too dark. Just perfect.
The build quality is super strong and solid. It can stand with a lot of things attached to the main body, the riffle, the bazooka, the shield, and the 6 big panels.
The articulation is another awesome point. I remember Barbatos MG, this kit has the same great articulation. You can do a lot of poses and at the same time you can attach all the things that this kit has, weapons, shield, panels, etc, and still, it can stand and be solid.
