Not bad but there are a few problems. I'm assuming the connectors are standard .1 (2.54mm) spacing in which case all your svgs are scaled incorrectly (most important in pcb, but very desirable in breadboard as well). The pins don't align on the .1 grid in either fritzing or Inkscape (which I use rather than illistrator) and they need to so that the board would fit on a pcb if you were to produce one. There are also problems (and extra pads on the top copper layer that shouldn't be there) on the gerber export files. This is probably because there isn't a copper1 group in the pcb svg file. The drill size is set to .035 rather than the .038 that is appropriate for .1 square header pins. In schematic the part is again not aligned to the .1 grid when it should be to match other parts and most of your pins look to be missing a terminal definition (the gnd pin looks correct the others connect to the middle of the pin, typically because there isn't a terminal value set). In this case the terminals are set in the svg file but not in the fpz file. They aren't quite correct in the svg either in that they want to center on the .1 grid position (I usually use a .01 rectangle with both x and y start coordinates offset by .05 inches such as .095 for the center of the rectangle on .1 inch). You can see the lack of the terminal definition in schematic by dragging in a .1 connector (2 pin is fine) and offsetting it slightly from the pin and connecting a line to it. On the ground on the top right corner (which has a terminal definition) it connects to the end of the pin as is desirable. the raw connection below it connects to the middle of the pin as it lacks the terminal definition in the fpz file.
