Read your work. Amazing work by the way. You wrote a very interesting dynamic between the Gabriel and August. Even George seems very cute. Also, the dialogue is what I would expect from a superpower series, and I can see it happening in real life if we had a hero society like that. The premise is really exciting and I can't wait to find out more about August. It seems like something happened to him in the past.
If there was something I would fix, it would be that you sometimes explain after you've already shown the character's personality traits. For instance, Gabriel seems like an impulsive, hot-headed person who wants a little fun in his life. I think you've clearly shown it, so when you explain: " he didn't sit patiently and take feedback.". It feels a bit redundant as all the examples clearly show that he's that way.
Have more confidence that you gave explained your characters well.
Also, pointing out a bit of inconsistency in speech. (I might be wrong since I didn't create the character) August first introduces himself and his power with a quick but formal introduction. This is good, as it gives him a more formal, "Stick to the rules" kind of feel as he says: "Telekinesis, with some light transmutation for flavor."
However, when he introduces himself to George, he says: "Telekinesis with ancillary transmutation.". To explain, I feel for this character as my guardians would also insist that I call them by their formal title outside the house, so I can identify a bit with August. Therefore, I feel like it would be out of character to suddenly switch up the greeting, as someone with that sort of upbringing and outer personality would have a preloaded response to general situations like introductions. It might be better to stick to one set greeting unless you have a reason otherwise.
Besides those small things. I really enjoyed the series. I hope to read more when I have more time!
