Look ---> See

[uniface]

Sometimes flakes are not just debitage (waste flakes removed in the course of making something).

Proverb : "Everybody looks. What you've got to do is learn to see."

This is a really nice example of going from the first mode to the second, written by a beginner, noting the features of a particular type of flake that identify what it is and why it was made.

(She could/IMO should have noted that, as shown in the last picture, a striking platform was carefully isolated & relieved in order to enable it to be struck successfully).

So what does this piece tell you?
Is that concave area at the top of the first picture the "percussion bulb"?
Making it the ventral (inner side)? (I think I have that wrong)
Or is this just debitage?

First pic is a negative bulb of percussion from the removal of a small flake. Bulb of percussion is in pic 2. Not well defined but that's the bulb from the removal of your whole piece from a larger core. Gary
