Thats amazing man. Probably add correct grammer to make it 'official' and proper. For example, add a period/exclamation mark after "BACK" and add commas after 'Second' and 'Finally' (Also, heads up if you want to know: "Firstly, secondly, thirdly, etc" are actually wrong grammer. It's just supposed to be "First, second, third, fourth, etc".
I'm in ap classes so its probably whats making me give all these corrections, but for something like an official blog or an essay, its usually better to say "In addition" or other advanced transition words instead of numerating your points with first, second, third, and so on.
Otherwise, it's awesome!
