Well done, and welcome.
Since the speed thing has already been address, the only thing I'll say is that I feel that a little more clarity on the part of the powers/abilities would be helpful. Clarity in general, I mean -- the explanations leave a great deal to be wondered.
There are tons of different mental images. I can think scientific and say light powers would allow you to excite electron shells in atoms and cause nuclear reactions. Classical magic would tell me you can create beams and balls and other things. Other interpretations might lead to...???
Again, well done overall. Also like that you have a good solid grasp on the writing style you plan to use. Sometime in the future I think I'd like to fight you.
