Looks fabulous! You are much better at the graphic art side of this than I am, hopefully we can convince you to keep making parts 
. I only see two issues at a quick look both connector related: it is desirable (but not the case in many parts) that connectors start at 0 and go up in sequence to the number of pins-1 which isn’t so far the case here. The reason is that Fritzing is expecting (and assumes) the next pin will be sequential when it creates the labels from the fzp file. If you have connector6 (pin 7) label x, no connector 7 and connector 9 (pin 10) label y if you hover on the pin in breadboard pin 7 will show label x, pin 10 show pin8 (which doesn’t exist) and I think a random label (it may be pin 11 which will show the random label) and then it will recover and label the pins properly. A minor issue but annoying and not correct. The other issue is that at least connector16 and 17 on the battery plug aren’t on the .1 grid, but over all a beautiful job.
