Hello!
First of all I would like to congratulate you as a fellow programmer for the work you have done. This thing is a beauty!
Being a spanish native speaker but with a great knowledge of the english language I was thinking spanish speaking people could find your work useful as well, and wanted to offer you my help for free as a translator, as I don't think it would take much work (from english to spanish as I haven't learnt other languages).
This would make your city generator reach a wider audience and thus help more DMs around the globe on this heavy duty that is world building. Feel free to contact me if you like the idea :)
