Hey so I love the concepts. I think you have some really creative ideas and also a good hook for people to come back to. However, since you wanted criticism, I'll have to dish some out. You need to focus on showing more than telling right now, especially as a new writer. Whilst the idea of "show dont tell" is inherently flawed, it still helps newer writers understand things such as pacing and structure, which sadly your piece just don't have yet. You skip through events, which is sometimes okay, but in the situation you've written doesn't particularly work, since we need action and visual description.
Try planning your scenes out in a standard way (this isn't always standard but it's good practice), introduce the setting, introduce the character (you can switch these two since you're writing in first person), explain a little of the context of the story (like people having superpowers and a little bit of your characters backstory), but then show the rest. The pacing is way too fast right now and you need to slow it down. This doesn't mean padding it out with crap, it means actually exploring the scene, exploring the emotions, exploring the characterizations. Don't tell me things such as the man has a heat related power, show me it with the pain it inflicts or the ripples on the skin. Describe people in a way that isn't about their clothing, clothing is important sure, but what's more important is their face, their body type maybe, do they look friendly? Hostile? Explore that and have your character react to his environment, not his environment to him.
Sorry if it's a bit much, I did enjoy the concepts quite a bit and I see potential. Superhero novels are always fun! But you need to show us the content.
