If it helps, I've written a blog about composing Twitter pitches (I got a book deal from the #PitDark contest). Here's the key info below for you:
I highly recommend reading
Dan Koboldt's pitching tips as a starting point. It is also good to research pitches that have done well in previous contests and unpack them to see if yours can follow a similar format. However, if you're short on time, here's a basic outline I've come up with, using my book as an example:
- Character + situation/story trigger: Lyss, she's bound in blood pact with a monster.
- Desire: Get to Illredus to break the pact, find her father's killer.
- Obstacles: The physical distance, the monster, the empire's soldiers hunting her.
- The stakes: If she doesn't break the pact she'll go mad, if she gets caught by the Empire, they'll execute her.
From here, I mix and match the order/elements to create different pitches, such as:
Lyss's bound in a blood pact with a monster [character + situation]—a forbidden magic punishable by death [stakes].
Her only hope of survival lies in the city of Illredus [desire].
But first she has to drag the less-than-amicable monster across the Empire [obstacle] and try not to go mad from it's magic [stakes + obstacle].

Twitter pitching 101 but be aware the information is a few years old now.
