First time sharing here!

I really liked the design of Calibarn so I finally decided to get one of it and build over HG Barbatos Lupus and RX 78-2.

I also did the panel lining, though I feel like I can do a better job on it, I still am quite satisfied on how it turns out ????

I'm planning to get HG RX 78-2 for my next build but there are a lot of version out there and I'm thinking of getting the Origin ver., is that like the current best HG RX 78-2?
