Dear bro, I'm going to be sincere because you deserve it, you want to walk the writer's path and, also, as a form of respect for your hard work. I already observed in other occasions that you've got a rich lexicon and I can see that your writing style is flowing and pleasant. If I have to focus on a constructive critic - merely said as a reader and without any pretense - you depict a classic apocalyptic scenario and probably you could concentrate more on some original scenes or elements. What caught my attention were the super-flares rain, but it was only at the end of this first episode. Your descriptive parts are well built but I would consider distributing the information in a more gradual way or starting with a "hook" for the reader. A particular scene that catches the attention from the beginning. Having said this, you've all my sustain and I feel that you've what it takes to amaze us.. I'm looking forward to reading your other episodes! tip!
