I was amused that one of the first responses was to criticize the projection he chose. There's one in every crowd.
Which is why all Wikis use these projections, or variations thereof, as standard base map (and it looks as if he just took at Wiki base map and colored it)
While we're on the subject of map projections, I would suggest taking a look at the Authagraph projection.[0] It preserves the size and shapes of all the continents while simultaneously giving the viewer vertigo.
This article has bigger ones:

That doesn't sound like criticism to me, it sounds like a suggestion. Maybe the person was just curious.
