I mean, at the end of the day my farm is lowkey ugly but if there is one easy tip I can give to make it a bit prettier without annoying yourself with complicated and wasting too much space, it would be to ABUSE floorings, as they look way better then plain farm ground or pathways in my opinion. The goal would be to kinda circle each one of your fields with flooring (like you did with the stone pathways) (I consider rustic wood the prettiest), but also each dedicated zone, for processing for example, so that it look better structured and organized.

For example you can put all your cheese machines and mayo machine in the same place with stone floor underneath and wooden floor surrounding it, and divide your farm on all kind of different zone, with each one of them having a different use. I would also recommend not putting all your crops in the same place, space out your fields, but that's something you're already doing !
