Duolingo Empty States

I really appreciate your boldness in selecting Duolingo as a starting point!

In terms of the copy, structure, and information—well done: the user clearly understands what’s happening on the screen and what to do next. The title and the button work well together.

However, there are a few things I couldn’t help but notice:

• I’m not quite sure about "keep improving" in the last one; the user might not have done anything yet, so there may be nothing to improve.
• I’d suggest reviewing the closing punctuation: consider reducing the number of exclamation marks (as they communicate strong emotions and can be excessive when we’re simply informing users) and removing periods. The interface will look neater that way.
• Lastly, it doesn't quite align with Duo's brand tone and voice, which is more upbeat, referred to as "playful" and "expressive." The wording you've chosen is more neutral.

In a nutshell, it might not be ideal for Duo, but it's still quite viable. Keep it up!
