Thanks for the comments guys. Good feedback. The grey square represents tin but any metal really as they may explore for more resources in the future. Commbank? A little, sure but not a bad thing eh? Banks' logos are designed to look solid and dependable. I might send it to the company on spec. I'm a freelance graphic designer and could do them a decent website too (god knows they need it) but I might see what they think of this first.
