A pitty, I like the Miui5 icons much more, because I'm not much into the current flatness craze, they do a disservice to today's screens (e.g. the O+O theme is absolutely horrible) and will surely fade away fast.
I'm not talking about going fully skeuomorphic, but gradients, shadows or a glowing effect, when well done can do much for a design, adding depth, 3D or at least a 'bump' feeling, evoque interactiveness and even sexyness (the sexyness Steve Jobs complained the 90's Apple didn't have anymore).
Today's flatness is just emptiness, sometimes with ugly colours to go with it. It's "clean" alright, though in a bad way, because it's devoid of everything.
Anyway congratulations for your good work, specially that exclusive Mi5 Holo theme, it looked great
