Self-Review of My Fanfic, Poisonous(PART 1)

I have decided to give myself some self-reviews of my fanfic(that you should read, comment, and review), Poisonous. This way, I can adress how I think I have done.

WARNING: SPOILERS MIGHT BE PRESENT.

The most important one I'm starting off with is about the ocs present(it's an oc fic):

Personally, I think any bystander who randomly reads this fanfic is going to think that they're Mary Sues. I haven't fleshed out their characters too much at this point, and since I haven't introduced any other new characters yet(Colorful Sound hasn't met Fawnette, Flora, and Windi yet, and I haven't figured out what her first impression of them is yet), they'll seem kinda flat. Which is what I worry about. When those three mares meet Colorful for the first time, I'm not going to waste the opportunity to show more of their personality(and if I don't, LET ME KNOW AND GIVE ME A SUGGESTION ON HOW TO MAKE IT BETTER).

I'm currently debating on whether I introduce the main 6 or not(they don't have a significant role, despite the starring ocs going to Ponyville). I might introduce Rainbow Dash, because Windi admires her, but she'll probably call Windi lame. I think it'll be good angst fuel and character development fuel >:D

My conclusion on this part: MOAR CHARACTER DEVELOPMENT.

That's my main worry there, but here are the other things I could have done better on:

Balance between dialogue and description, since my narratives tend to be dialogue heavy.

Wrapping up scenes without it feeling rushed/too slow(the fight between Flora and Fawnette comes to mind).

I'll try to do better!
