You have an extremely aggressive and impressive design that I believe will go far.
It is so good I am limiting my requests to letter tweaks and color shifts.
1) The letter J "goes back up" I would like it to not do that. Change J so that the J looks like a backwards L with more rounding at the corner. I can draw if there is confusion.
2) Same with the letter C. Please make it so the letter C looks like half a square with rounded edges.
3) Letter L cut off the corner
4) Add whitespace so the flight path is not touching the "ball"
Here is some guide
