India's Population Density Map
Source: http://www.gisdevelopment.net/policy/india/technology/mi04018pf.htm
This is an India's Population Density of 2001 Map. The legend is good. It clearly shows what each color means. The map inset emphasizes how dense Delhi is in terms of persons per square km.
For the color, I think it would be better if the cartographer used monochromatic because this type of color gradient gives smooth color transition and would help the map reader compare the density of areas without looking at the legend.
For the label, it would be better if the color of labels are black. Because there is a color green on this density map, labels would be easier to be read if they are darker.
Spacing is not evenly distributed. I noticed that the space between the title and the island is so small. Overall, this map deserves a rating of 7.

North Brazil's Climate Map
Source: http://mapsof.net/brazil/static-maps/gif/brazil-norte-climate-map/full-size
This map, just like the other maps, has no map title. So I relied on its website to understand this one. I also used the Google Translate to understand its legend.
According to its website, this is a map of North Brazil's Climate. Yes, there is a legend but this map is still difficult to interpret if the map reader is not knowledgeable of Climatology. In addition, its legend is written in Spanish. Therefore, this map would only be useful for people who can understand both Spanish and Climatological terms. Furthermore, legend for the lines indicating temperatures is not included. The reader might be confused of these lines.
On the other hand, it has used good colors. Areas opted not to be included are colored gray. Also, it might be helpful if some areas are labeled or, maybe, a map inset is included to help the map reader recognize these areas.
All in all, this map would be better if the cartographer has included the map title (and also, a translation of it), a direction, and the sources, too. I would give this a rating of 6.

Precipitation and Temperature Map of Australia
Sources: - http://www.bestcountryreports.com/Precipitation_Map_Australia.html
- http://www.bestcountryreports.com/Temperature_Map_Australia.html
The blue map is the Precipitation Map of Australia while the red one is the Temperature Map. These are choropleth maps which show the annual mean amount of precipitation and annual mean temperature in Australia, respectively.
Colors used in these maps match the message they want to interpret (blue for the amount of precipitation; red for the temperature). In the Precipitation Map, It used a blue monochromatic color to show the relative intensities of the precipitation in the areas. The lightest blue signifies the lowest amount of precipitation in inch/year, while the darkest blue signifies the otherwise. In the temperature map, it used a red to green dichromatic color to show the variation of temperature from the hottest to the coldest. In this case, the green signifies the coldest annual mean temperature. Colors also do not clash or clutter.
Place names are labeled on some significant places on or near the coasts. Territories and water bodies are also labeled to guide the map reader.
Important elements of the map are provided. The title, legend, scale and direction are all placed in a box below the map but the spaces are still balanced and appropriate. The two maps' layouts are both excellent. Significant data are all sufficient.
I would give these two maps a rating of 10.
