This is a great logo. It really looks authoritative and captures the natural beauty of the area including the billy buttons. The color combination is also quite good. I prefer the lighter grey version (#6). I think the layout is a bit restrictive in that if we were to place along a number of other logos in the publications, in a footer, or in the banner of the website, the elements would be shrunk too small. Perhaps if the text were placed to the right of the circle. Then adjust for size (now you have to OO in a line) or incorporate the circle to the O of OzTEX? Would like to see the green lightened also, and the mountain top rounded - our maountains aren't that high in Australia on the whole. Either round the top or widen the peak. I am looking forward to working with you on this one mambo, like your style!
