Belt is much more difficult to assemble right than what we would expect from it. It's really easy to screw up this part. At the time my brother built his suit i wrote a tutorial for him, and it ended up making almost 2 pages without being fully complete
And i'm so pleased you finally decided to handpaint your helmet. I'll be honest, when i saw you used decals i cringed, but then i saw you removing them and get the brushes and i'm happy now
And don't worry i developped an OCD too when painting. It was to always fully check the helmet twice or three time after each pain session, to be absolutely sure i didn't make some unnoticed fingerprints on it and to not let them dry.
