A book cover for an ESL self-study guide to English small talk with exercises and answers

This is what a business in United Kingdom was looking for in their book cover design

I need a book cover for an ESL self-study guide to English small talk with exercises. It has useful phrases, idioms, and vocabulary in it but I will provide the blub for the back of the book. I would like a simple design. I had the idea to use a red background and the letters 'English' being large across the front in Union Jack lettering then 'ESL' below in different lettering and Small talk further down. I am not sure if the Union Jack lettering will stand out well enough on a red background so we might have to use a different background or edging for those letters but Ideally, I'd like the book to be red and either the 'ESL' or 'Small Talk' to be a vivid blue but again if something else looks better go with it. If it looks like this design idea doesn't work I am open to other ideas too. If the Union Jack lettering is not used I will need a Union Jack on there somewhere to show that the book is in British English. Those are my ideas but ultimately, you guys are the professionals.
