Another amazing map! And like Hoplitesoldier said, the information is extremely useful as well (the map would be very hard to understand without it).
However, I'm not sure your choice of colours was so good. The colour used for allies of the Delian League is most similar to the colour of neutral states rather than the colour of the Delian League itself, making the map hard to interpret at a glance. Also, the colour of the Delian League is a little too close to the colour of the sea. I think navy blue might be better for the Delian League, and maybe a shade of green for their allies...
