It took me a month to respond? Yeesh.
Actually, that kind of answers the first question. I haven't read a Pokemon fanfic without the intentions of reviewing it in over a year. So all I've read are ones that very clearly need improvements. You could try the Fanfiction of the Month list, which is the best of FF&W as voted by the community. If you want to read a bigger variety than just what PC offers, I'll find the list my friends suggested for me that covers various sites.
As for your own writing, my only suggestions are:
-Grammar could use a little cleaning. There weren't any major mistakes that were distracting. I only found them when I went looking for them.
-More description. I don't know if maybe it was from the format of your post (since it's not actually a story but it still is), but I would have liked to see more of the character's thoughts and feelings. This got better towards the end of the entry when Cheryl died, but it was missing a little in the beginning. There's also the advice that Pokemon battles could always use more description to make them interesting. Up the stakes a little. This will also add to the Pokemon's personalities so that their triumphs and possible deaths hit the reader harder.
I hope this helps and makes a little sense. I can explain more if need be. If you have any other writings, I'd be willing to look them over and hopefully respond to them sooner than a month!
