Its great to see a new mapper.
And landmarks are a great thing to map. It looks a little flat and sparse for a TCE map, but I like your thinking.
My advice would be to play lots and lots of TCE and study the maps. And you will see whats needed to make a really great map.
Look at how maps like delta and north flow, see whats in common with all these maps, look for what works and what you feel doesn't work and apply that to your map.
GL on your new skills and show pics your map as it develops
One last pieces of advice, its easy to start a map, but it take big cojones to finish it!.
