Delphi Self DevelopmentLogo Design Contest

Hi people, thank you for your works. I appreciate your quick responses.
Here are a few remarks from what I see.
1. I will not choose a logo that contains "D" in the centre. Instead please try something that is a "stone" in the centre.
2. Please feel free to use some other colours too. Do not have to use orange and grey. The only colour that I don' t prefer for this logo is RED.
3. I also like some "raw" figures.
4. Please do not use any human figure, especially "jumping" "hugging" etc. as a cliche for coaching business :)
5. I think it is better to use a more bold colour for DELPHI instead of "Self Development"
good luck.

Thank you for your designs. In the myth of Delphi the most important figure is the stone that has been said that the centre of the universe. So it is better to emphasise the stone instead of the eagles. Or stone can be in the centre of eagles. Please use any colour. Except red and green.
