Based on the provided criteria and evaluation standards, I would assess the essay at the second tier, with a score of approximately 20-24 points. Here is the analysis of the composition: 
 
**Content:** 
- The invitation clearly states the purpose, time, location, and activities of the party, covering the essential details. 
- The writer expresses hope for the recipient's attendance and wishes them well, demonstrating polite and engaging communication. 
 
**Structure:** 
- The structure of the email is logically organized, with a clear introduction, body, and conclusion. 
- The email format is appropriate, with a greeting, main content, and closing. 
 
**Language Use:** 
- The language used is mostly accurate and appropriate for the task, with phrases that effectively convey the message. 
- There are no significant grammatical errors that impact understanding. 
 
**Minor Issues and Suggestions for Improvement:** 
1. **Spelling/Typographical Error:** The closing should be "Yours, Like" changed to "Yours, Mike" or another common closing, as "Like" appears to be a typo. 
2. **Style/Formality:** Consider using more formal language, such as "I am writing *to* invite you," instead of "writing this email." 
3. **Variety in Language:** Introducing more varied sentence structures and vocabulary could enhance the sophistication of the writing. 
 
Overall, the composer has successfully completed the task, expressing all required content points clearly and effectively, though some minor adjustments would polish the presentation further. |
