Here are some of my concepts. With all of my submissions, I've gone for something that's fairly clean and simple, yet striking. Some I've created an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons. Others, instead of creating a separate icon / typography combination, I've created an all encompassing logo / unit. One that can be used for additional elements just as 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.
