Nice to see an English speaking customizer on RU-vid. The final result was amazing. I do my fair bit of custom builds as well. Mostly just repaints, but I've gotten into scratch building with pla plate more recently.
delpi decal is a great brand, but some of their older prints have a harder time sliding off the backing. their decals are super durable too so there is little risk of tearing
Thought I'd write a quick snippet about this since it came to mind: "The X-EX-02." "I thought the Calibarn was the only experimental Gundam." "You'd think that, but apparently someone managed to scavenge the original prototype of what would have become the Lfrith." "So, 02. Besides the obvious, what's so 'experimental' about it?" "Besides being stolen and refurbished? It's pilot is one of only two known people to be able to operate the Gund-format without data storm interference- though, this was discovered long after the 'Incident.'" "Oh boy... Heavily modified for war, vanished to space for years, the pilot is immune to it's downsides... What do they call it?" "The Tempest, and if you thought the Aerial and Calibarn were powerful... You haven't seen anything."
