Cool stuff. I found the player a bit jakey as well, but your second link seems better.
There is no basis for comparison, I find, when one attempts to "critique" a classical/symphonic composition. Is it Beethoven or Mozart or ??? ? Really, what's the point of a comparison? What you have created is much more like a fingerprint, very individual and idiosyncratic to you.
You have amassed quite a collection of musical ideas, which is impressive, and have arranged them into a symphony, which is even more impressive!
I would say, to do what you have done takes, and here I paraphrase Mahler, "utter balls." Nice work!
cheers,
