Logo Refresh - Cleanup

I already have a logo I’m happy with overall; it just needs a careful touch-up rather than a complete overhaul. What I’m after is a slight modification. Please clean up its current form and introduce a bit more detail so it looks sharper and more contemporary, yet still unmistakably the same brand...
