Having problems with displaying density map

I am using a shapefile from the European Commission on world maritime traffic. They have developed a map of maritime traffic as shown here.

 

I would like to replicate the same map on ArcMap 10.3 so then I can zoom into Europe and use my map as a discussion for a research paper on the European maritime industry. I have downloaded the point shapefile of the data from the European Commission site. When I add it to my map document, there are lots of uniformly spaced dots as shown here.

 

So then, I tried to use the Spatial Analyst tool to better depict the densities. I went to Spatial Analysis -> Point Density -> Used the point feature, Output Cell Size: 0.716, Neighborhood: Circle, Neighborhood Settings: Radius: 6, Units: Map. I then made an edit in the Properities -> Symbology tab -> Natural Breaks. Now my map looks like this, but it does not quite look like the map that the European Commission made.

 

Any ideas on how to fix this would be really great!
