Here Is my submission i chose the combo of light green and grey and also used a nice slightly playful font. I used a claw mark as the symbol as the others seem to be usin paw marks which dont really stand for claws. I also have the word claw to have a slight seperation in colour to show law. I got the shape of the rounded square from the way the icons appear on the iPhone Menu. Any queries or ideas on colours or variations dont hesitate to contact me.
