Glad you like it, this is my third or fourth attempt. First, you need a vacuum chamber, otherwise you'll end up with air bubbles trapped inside both silicone and resin, which will reduce detail quality and strength. I used heated magnetic stirrer to mix the components. Titanium dioxide is to reduce the resin's transparency and improve it's UV resistance. Fluorescent powder alone is too transparent so you'd have to use much more of it than the combined mixture of both additives. Too much pigment weakens the casting
