Hi Kira,
Thank you for submitting your threads for perusal!
I've gone through the threads you've supplied as examples (and I appreciated the knitting joke), but I'm sorry to say that I don't think what you've provided here are sufficient examples for expert Kinetics.
These skill requests are a way for staff to evaluate your understanding of the skill, arcane or mundane. We need to see that you know and understand the nuances involved with the craft, and how you are applying them in your threads, and that you can utilize them at a high degree. It's not just the character's physical limits that you're pushing - which is also important - but the limits of your knowledge and understanding with the concepts.
What I was really looking for here was detailing of technique and the interaction with the Aether Flux. Your fourth thread, in which you utilized the technique of Splintering, got the closest to what I was hoping to see. As a journeyman, you have a number of techniques at your disposal, and I would have liked to have seen you combine them to consistently demonstrate your understanding of the skill in question.
For example, in your third thread, where Kira lifted a car and dropped it... even though her opponents were able to use earth via a dragonshard, Kira should still be able to sense exactly where they are on the Aether Flux with Aether Sense. Not having eyes on her target is not an impediment to a Kineticist. Something she could have done here would have been to not only Lift the car, she could have used Splintering to explode or implode the earthen wall that they had made (or force them up over the wall they had created with the same technique), dragged her victims out using Pull, and slammed the car back down on them with Push. That would have been a demonstration of four or five techniques that came together.
Please don't feel discouraged - magic, especially, is incredibly challenging to learn. This is as it should be. But the more you practice it, the more you familiarize yourself with it, the better you get. This is also as it should be.

Keep writing, keep improving, and when you're ready, feel free to apply again.
Please don't hesitate to reach out if you have questions. That's what we're here for!
Kind regards,
Talisman
