Thinking about writing story

I was thinking earlier, and I decided I am going to write my 1st story. I got the idea from my little brother. So anyway, it may include the CMC. I know, however, it WILL be a comedy, maybe a bit of romance here and there, but mainly comedy. And I will accept dislikes, as long as you put in comments what made you not like it. And it may include a few oc's like Thunder Chaser, Raincloud Clearskies, Flare Roller, yadda yadda yadda.
I've seen plenty of people have great stories as their first stories. Ex. Nyx's hearts and hooves day.
