Further development on #72, however you now rank #73 higher. I have made the water drop character bigger in this version and altered the colours and shading on PlumbCool. I've got to take the dog for a walk now so I won't have time to do anything else before the competition expires. You can extend the competition deadline if you wanted to.
Thank you for your time. I am really torn between yours and the one I have ranked 1 currently. I like # 78 Best as it is very readable. I will have to make a tough decision and may have to make an offer to one of you for the second place design. :D
