Honestly, and sorry for being harsh, that SU could use a fair bit of work. I'd recommend trying to get about two small paragraphs for her appearance and personality with more still for her history - I know I said brief but try looking at the other SUs for example. You also don't really discuss her motives for anything which would be nice.
There's also already a character capable of communicating with pokemon and one with a ralts. There's no rules aganst sharing talents or pokemon with other charcaters, but I figured I should let you know in case you want to go with something a bit different, either way full ESP would actually be really difficult to RP and could be potentially overpowered considering the nature of pokemon battles, so I'd recommend toning her gift down a lot if you intend to keep it.
Sorry if this comes across as harsh, but you will still be a welcome member to the RP once you fix things up. Your reservation will continue for now, but please try to have your SU complete before it ends. If you need any help with your SU feel free to VM or PM myself or my fellow GM Scyke'd - or even one of the others taking part in the Hoenn Diaries if they are okay with it. :)
