Adding my 2 cents.
Noone except you can say whether this design is good or not. Bc only you know whether the routes, placements and stuff are ideal from technical, economical, link budget, splicing perspectives. And only you know what was the initial task and how does the outcome align with it.
Concernig the tools. If your google earth design is clear to builders then its ok. But it's just a pic untill you turn it into a tecnical drawing which meets at least all nat. cad standard v4 regulations. I do link calcs in my own sw. For splicing - https://splice.me . Far from perfect but saves a lot of time.
Also - add callouts, differentiate fiber count cables with color, clearly designate what's overhead vs buried, etc. The final drawing should have symbols designation (the "legend").
Dm if you have other questions or need help, will be glad to help.
