@caffeinatsun Finally done with your review and I'm sorry it took a while. First I'd like to say that I was really impressed by your story. The events really flowed together so I could tell there was a lot of thought put into that. You also have a level of polish here that's not common with web novels which really made yours stand out. Your descriptions weren't overdone but very vivid which helped pull me into the story. Your dialogue is also very natural and has a great flow to it. Now I'll touch on some of the things you requested:
Action Scenes
I'm probably not the best person to comment on this since I'm also not predominantly an action writer, but honestly, I thought yours were very well done. That first chapter really hooks you in with the thrilling and gripping action you have there, and that torture scene was just so well done. That scene in particular stood out to me since it was so visceral yet tastefully done. I like how you revealed elements of the MC and Antione's character instead of just making it an old gorey torture scene.
Characterisation
I'd actually have to agree with your point about Elanaâs personality being a bit more slippery than the side characters. To be, she felt like a pretty good MC with a unique struggle with her magic (or lack of) and that torture scene really makes you emphasise her off the bat. But I will say that she did feel slightly more lacklustre compared to some of the side characters who stood out more, specifically after Antione's introductions (as you could tell from my comments. I adore him). She's not badly written in any sense (honestly, you still did a good job) but she just didn't stand out as much.
This is definitely just my opinion so feel free to take it with a grain of salt, but with Antione in particular, there was just so much character and charm to him that I didn't quite get with Elana, and in a way, he did overshadow her for me. I thought about why this might've been the case and for me, I think it's because of how passive Elana is initially. I understand that's mainly due to her being forced around by her family and stuck in this stifling environment, but that did make it feel like she had less agency compared to some other characters.
However, I do this being something that could give way to some great character development down the line. But, it might be something to keep in mind at the start if you want readers to grip onto her like some of the other fantastic side characters you've written.
Overall, I found your novel a delight to read. The story is really gripping and the characters really do have this great charm to them. The criticisms here are mostly just my personal thoughts and you can take them as you'd like. Keep it up because you're doing great and best of luck with the AFT!
