: It was fine at first, but you rushed into the battle quickly. You should have like, let a day or two pass, describe what happened during the few days instead of just meeting a Cyndaquil like that.
Another thing: Where exactly are you?
: Poor. Very poor. Capitalize names and first letter of each sentence. Don't overuse capital letters and exclamation marks in speeches, they make your story looks messy.
: Poor. Describe your surroundings, describe how you feel when you're battling, describe practically everything you can. Use lots of suitable adverbs and adjectives, they help your story a lot.
: Why would a Cyndaquil throw coconuts at you with no reason, anyway?
: Barely enough. You need a much, much longer battle than this for Cyndaquil. Throw in LOTS of adverbs and adjectives, describing your Pokemon and your oppoent after they made a move. Also, don't just shout attacks, maybe get your mon to do some stunts like climbing up a tree and firing attacks from there, which makes the battle much more exciting.
Outcome: Cyndaquil not captured!
