We love the simplicity of your designs, and the strong color contrast! #19 is our favorite so far because the bridge image is clear and bold, and it would look good even in a small size.
We like #20 also, but the colors in #19 are more vibrant and appealing to children. Also the image in #20 seems a little more grown-up, like something for a pharmaceutical company. Still, they are both excellent!
We like your design (#19) with the original bridge we asked for. Would it be possible to try a similar design but with a different style of bridge? I realize that this is the one we asked for, but someone made the comment that it could look more like a wishbone than a bridge at first glance. We are open to any style.
