I like #40...but I prefer other symbols in the circles...how bout just English letters as I work w/ kids who are learning to read and spell in English.... (I do like the look of the different letters in yours, just don't think they communicate the right message for me...)
thanks for tweeking, it i prefer the look of the first one but the different symbols don't really fit my practice. I like the ratio of green to purple and white, like the size of the graphic and text. It has a balanced look that I like.
My concept is based on your suggestion to show "Read, write, speak" upfront and easy to convey the idea of your service "Letters" coming out of house chimney show "in house" service.
