A couple small things:
1)
Due to gravity, slight differences in density began to form large gas
Should be "large gas clouds" or "large gas nebulae". Most people probably got it from context, but just in case someone was confused.
2)
I would also add that in normal "stellar nucleosynthesis" , iron is the upper limit for fusion. Heavier atoms aren't able to be produced produced until the star goes supernova, during "supernova nucleosynthesis". Also, a supernova is basically a gravitational collapse followed by a ridiculously powerful explosion.
But yeah, it's hard not to go into too much detail when you're trying to explain complicated Science topics. Scientific Knowledge is fractal, you can always go a bit more in depth to present a more accurate picture, but it requires an exponentially growing amount of background information. Plus, it's always growing, continually being updated and improved.
