I like the simplicity of the design and I like the idea of playing around with letters. However, what is the thought behind the circle figure before the letters?
yes, but unfortunately contest is over and only #1 designer can submit new entry's during judging mode. Why not giving 24 hours extra time to this contest?}
I like the new ones - could you please experiment a little more - try to keep it simple (as you have done with the previous designs) and as friendly as possible.
