Here are some of my concepts. I've gone for something that's fairly clean and simple, yet striking. Creating an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons or watermarks.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Firstly thanks for the great feedback, always appreciated. Secondly apologies for the removal of the 1st ranked entry. Another designer pointed out that I'd forgotten the icon was just in an older competition - however I have subsequently removed the other entry completely so this is the only project its in. My apologies for any confusion or issues.
Regarding the 2D version, not a problem at all, and here it is.
