About Entry 7, could you change the bird into the shape of a trowel combinated with a handfork or something. To show that Dewit is about tools and not about other gardening stuff.
Here is the logo with tools, but the reason i choose the blackbird in the first logo, is that if people see the blackbird in thre yard, they will symbolise it with your products, and becasue many tool companies uses tools in there logo, people has problem distinguages them. so a unike symbole is better the commen tools.
