I was working on (sort-of)replicating an image online and I ended up with a not-so-cool-looking version of an image in TikZ. And, since im an amateur tikz enthusiast, I relied on rehashing some old code and didn't do it from scratch. The end product isn't that great as mentioned earlier. So, I'd like to ask you for some help in improving (and extending) the image I have. I shall post the code below.
