I think maybe I cannot explain clearly, I dont have a claim like this my encryption algorithm is safest, fastest, best algorithm on the earth. I tried to make an 'unique' algorithm (as you call home made :) ) in an hour. I shared it in order to show there should be different approaches to encryption algorithm because if algorithm working principles are known and predictable, then algorithm safety level decrease. I think you tried to approach cryptography by an academic perspective (more stable solutions) but I tried to avoid stoling of the data.
By the way, I mentioned N=NP due to show probably in a few years there is solution of this problem and maybe the end of the bitcoin [1].
As your claim about brute-forcability, I want to say quantum computing is experimental right now but there is working machine and proccesing units of them. In other words, it is not only theoretical and Quantum computing age probably allows to crack these all algorithms probably mine as well with Quantum AI. However, in my opinion, if people do not know how your algorithms work, the attacking possibility is dramatically decreases.It is more difficult to target something unknown.
