I used the scripts of three Indian languages (those that I can speak and write) besides English for this work. The one that has the largest font is Tamil, my mother tongue (the one that my family speaks). The next sized font is written in Kannada. This language is spoken in Karnataka where I spent a major part of my life in India. The third one is Hindi - spoken by a large segment of the Indian population.
The scripts are used to just convey the names of the respective languages in which the words are written.
