Getting My Feet Wet In ArcGIS

So here we are, week 1 of classes and my first lab for Intro to GIS is complete.  I have to say that for an "overview" of ArcGIS and its basic functions, the lab was a bit more difficult than I had expected.  Finding some of the tools wasn't as intuitive as I would have expected for such and advanced and popular tool.  Because of this, I found myself reading the lab instructions many times over before I figured out what was supposed to be going on.  Perhaps there are some version discrepancies between the provided instructions and the current version of ArcGIS that is available on the eDesktop.  Ultimately I made it through and I created this awesome map:

This map displays the countries, and the major cities, of our wonderful planet.  The differing colors delineate the population densities of the countries.  You will also find some key tools at the bottom of the map such as the cardinal direction indicator, the map scale in kilometers, and the color legend for the different population densities.  

Now I am going to give a disclaimer and submit a request for suggestions.  I am color blind.  Red/Green, Red/Brown, Blue/Purple...it is what it is.  So if you see any colors that clash or just look off, please provide some suggestions so I can make it better.  I try to keep things along a single color spectrum or grey scale to avoid these complications, but I anticipate there will be maps in the future that are just going to look off.

So that is it.  First lab done and I am quite excited to delve deeper into ArcGIS and really see what I can do with maps.
