I updated my Google Map… It now looks very chaotically. Any ideas how to improve the look?

I am playing around with adding a Google Map of my trip (see the map section).

I still have to figure out how to connect the different points.

At the moment, I added the starting point in Münster, Germany and three possible train stops on my way to Hanstholm in Denmark. I am currently thinking about going to Holstebro and explore some of the Limfjord area and northwestern Jylland on my way to the ferry (roughly 100 km). Well, I have to think about it.

If you have any ideas on how to tweak an embedded Google Map, please let me know. Thanks in advance.
