Colin, this build continues to astound; even on a minuscule level with that 'lil Matrix - your skills are extraordinary!
The modifications you've made to Unicron's brain look superb with the lights, as do the additions of the 'flowing' energon crystals and finer details around the neck, collar and head.

Keep up the excellent work dude and do keep us posted on your progress, when and where you're able to.
