Oh I love the colouring in 12. The use of the cut-out background really fits too and just such a shiny icon. I also love the bright colouring in 15 and the added background just fits. And for some reason you make the colouring in 14 work, it gives the icon such a special and unique feeling. Great use also of the borders in 3 and 4 ans amazing text and font use in m ost of the icons with text, really. Beautiful!
