Thoughts on my accent?

Heavy foreign accent but very clear pronunciation. I don't know where you're from. Asia? Latin America? Lol.

First of all, you are very easy to understand. Yet there is a definite foreign accent. The words "dependence" and "quantities" are mispronounced and are giving you away. Also, the tone of your voice is much more nasally than the average American. I get the impression that you are speaking from the wrong part of your mouth. For example, I am learning to speak Spanish, and I realized that Spanish speakers speak from the front of their mouth while English speakers speak from further back. When I adjust my tongue placement and speak from the front, it is easier to pronounce many words. You should research if your native language and English have a similar difference, and if so, adjust accordingly.
