Interesting take on the genre. I thought it was gonna be something like Nightcrawler, but the light tone of the story works for a short story. Obviously, it needs more time cooking in the kitchen. It's a bit trickier since action scenes / the superhero genre in general usually rely more on visuals to deliver the beat with the right pace, compared to y'know, flat-out romance scenes. The CG at the end does the job, despite the drafty sentences.
Frankly, I have bit of a hard time reading the dialogue, especially with the viewpoints. Not sure why we can read Blacktail's inner thoughts, but not Finetic's, when the PoV-character is a complete outsider. Well, maybe not "really" an outsider because of the reveal at the end, but that part could do more fleshing out.
Regardless, congrats on creating your first project. Taking the first step is already half of the challenge. Hopefully, you will keep going and complete the story.
Cheers!
