Thanks guys, it's always good to have your work appreciated. the hourglass came from an Empire flagellant along with bits from 10 other kits (online bits stores are fantastic, and cheap, for conversions like this). There was an 'Eavy Metal masterclass which showed how to paint it that I followed to the letter. The same article had tips on painting crystalline swords for Eldar that I want to try on my Sword of the Herald objective marker at some point.
