That looks great! We would want to keep the "O" how it is in #48 along with the seperate icon above it with the A in the middle. Take a look at the link below, can you build an "A" like the one in the link to compliment the angle of the hexagon that it sits in? It would also give us a little differentiation from a run of the mill "A" at the beginning of "Atmos"
