By now you know to make settings such as Flatten Transparency, or the like, at "High." You also know about EPS. You should also know that 30ppi is completely dependent upon viewing distance, and nothing more, as far as perceived quality, . When I step back from my monitor and view your 30ppi parrot from what I believe a typical bus distance at the curb to be, the image appears to be fine.
Good luck.
