Good afternoon, Kitomyx!
Overall, the descriptions of your attacks work really well for the sphere you've chosen. I can already see the attacks in action, and imagine the reactions and effects that can be interpreted, and it's really good! I have only a couple things to address before I can give a trial stamp.
For the look of the senshi, this is going to be all CC correct? Or do you have the references? While you don't have to fill it out in it's entirety for approval, I am curious to know if you had any more ideas to share.
The overall range and duration of your attacks are on a bit on the large side. Specifically, for your Eternal attack, it makes a jump in range to 30 feet away from Clara, when typically a total of 20ft in diameter is the standard. I'd suggest to change the range for your Eternal attack to be up to 25ft in order to fit the shop standards.
As for the duration of the attacks, going towards 50 seconds starts to push into the pooling time for a night, rather than a Senshi, It's a bit large, as are the other times, so I'd recommend lowering the times to be 25 for basic, 30 for Super, and 40 for Eternal, since your Super is just a slight boost up, compared to hitting max power at Eternal.
Finally, for his eternal attack, while I understand what you were going for, you may want to change the phrasing from 'white fireball' to 'ethereal light', or a similar phrasing. We would like to keep it clear that no one identifies it as actual fire, as that would point towards a different sphere. Perhaps you can describe it as a burning fiery light, with fiery describing the color rather than it's form.
Once these are addressed, I'm happy to drop a trial stamp! Just quote me when you're ready.
Thank you!
