I'd say make it a bit transparent and turn up the specularity. Might look more effective if it was red also. The orange brown is kind of a neutral color. You might also see if you can round the edges off a bit also. I assume they're lattices, so go into the terrain editor and layer the edges out with increasingly dark shades. And the dribble that's coming from the bottle does need to be lowered, and smoothed a bit also. If it was me, I'd make it red, make it a touch transparent, then put a small radial light tinted red inside the bottle, inside the enamel, and see if any glow resulted

Talent is God's gift to you. Using it is your gift to God.
