I need 6 icons each in 5 sizes, 128 x 128, 64 x 64, 32 x 32, 24 x 24 and 16 x 16. The icons/buttons are similar. I'm attaching some samples of what we have (they're somewhat rough and need to be crisper and sharper). The background should be a shade of blue for all of the, just a different shade for each. They should be simple.
