I like the colors and the overall feel. However, I am not certain how a frog speak to quality web applications. If it has to be explained to me, I have no idea what I would tell my customers if they asked, why a frog.
Regarding the frog, it is not literary the frog connection to web development or applications but the I am looking ta the frog characteristics or ways to represent the company as a whole since it is going to be use as mascot. You may refer here for some of it : "When the frog jumps into your life it may indicate now is a time to find opportunities in transition. We see animal symbolism of transition with the frog in its unique growth cycle." More info here: http://www.whats-your-sign.com/animal-symbolism-frog.html
