I would suggest figure out what scale of map you want to try first. Global, continental, country, island, isle, county, town , street, campsite. The list is endless.
You starting well by hovering, but like previously said jump in the waters lovely.

Having checked out a lot of the threads your see there's some awesome mapmakers. Maybe try and figure out what you like that they have done, then incorporate it into your map.

look forward to seeing your first steps.
