Looks pretty good. A couple of minor issues: you are missing the schematic layerId, the holes in pcb are a little large, and the re are px in the font size. The lack of a layerId means the part won’t export as a pdf or svg, the px in font size will set the font size to 0 (causeing the text to disappear) when the part is edited by the parts editor. The hole size in pcb is 0.039999 where for a .1 square pin it should be 0.038. The easy way to fix that is copy in a pad from a generic header (which is the correct size) and then copy the radius and style parameters of the pad in to you existing pads. Alternately the hole size in Inkscape is hole size = diameter of pad - (2 * stroke width), where the stroke width should be 20 thousandths of an inch. Given the odd scale of pcb it is probably easier to copy a correctly sized pad from a header.
