Personally, i value larger creators crediting smaller ones and it's great that you value that too. Everything that you have done in this video is great and honestly I wish that more people would have the chance to see this.
I admit that I probably didn't have this view when I first started content creation... but over time I've learned how it feels to stumble upon videos of people using seeds I took hours/days/weeks to find, so the least I think a creator can do is at least credit them in the description or have their name on screen.
