Again not bad, but a few problems:

bb again missing the layerId

pcb

the hole sizes are wrong, they should be 0.035in for an IC  
yours are 0.027222 according to the gerber output.

fpz file

changed label from 4n25 to U to match other ICs

schematic

changed font to droid sans, and scaled it to make it smaller. In general schematic images want to be as small as possible to fit more on a page (and to match other parts). Again I also rescaled all the svgs to the standard scale as well
