Opinion on something I'm working on

Disclaimer: I'm not a professional graphic designer or anything. I did all of this with free programs. I know it doesn't look amazing or anything (yet!).

I've been working on this icon pack for a few weeks now. Criticism would be appreciated! I'm also looking for a good name. I've been calling it "Brix" without reason so far.

So far there are about 350 icons. (Not counting any bloat icons like numbers or excessive app drawer icons.)
