Miranda-
Your profile history seems to just be a 'she battled, caught these, lost'. I would prefer, I think, that your character had only been to Kanto - from her Pokémon levels this is much more realistic. Also, whilst she may have caught lots of other Pokémon, it would be good to focus on the three she is taking on board - how did she get them? What is their bond like? Give more details of them battling together other than 'got eight badges' etc.
Your Pokémon themselves are fine, I might have to check the moves but level-wise they seem ok.
Pending - if you could elaborate on the history to be more interesting than a list of achievements, then you will be accepted.
Also, try not to use so many colours, and if you do stick to dark ones rather than bright blues, faint pinks or yellows.
