Strengths:

Passionate & Engaging – Your excitement for mermaids, mysteries, and magic is evident, which helps draw readers in.
Personal Touch – Mentioning that you are putting yourself into a world you wish existed makes it feel heartfelt and relatable.
Warm & Inviting Tone – Ending with "I hope you enjoy it" creates a welcoming connection with the reader.

Suggestions for Improvement:


Grammar & Flow:

Your sentence is a bit long and could benefit from better structure for clarity. Here’s a refined version:

"I love mermaids, mysteries, and magic, so I created my own twist—immersing myself in a world I wish were real. I hope you enjoy it!"


This makes it more polished while keeping the original intent.



Stronger Introduction:

If this is part of a book introduction or story description, you might consider making it even more immersive. For example:

"Mermaids, mysteries, and magic have always fascinated me, so I decided to create a world where they come to life—a world I wish I could live in. I hope you enjoy the journey!"





Your original sentence has a great sense of wonder and excitement, and with slight refinements, it will be even more captivating!
