i have an 13hh Arab x welsh bay 3 socks a star shes got good conformation beautiful movement defently show quality, mare 3 and 10 months, quiet, loves cuddles such a softy. easy to work with [most of the time but she is a young horse has her tantys], well known parents, VERY smart pick up things the first time round, defently a jumpers/dressage/showy riders prospect, no doubt she will excel
she is a show off [gets jealous of my other pony always has to mimic her movements and make them better -.-']
she’s has inherited all the right traits from both breeds very pretty, but compact but everything is in proportion
nice long legs [not leggy] she’s fine but for her breed she exactly spot on
i would say she would suit small adult/teen pony as she will be too forward for a beginners/child’s pony,
as that’s the way she is, defently a competitive pony with heart of gold
she is a good doer 
will hold weight but with the right balance of diet founder wont be an issue
im thinking about selling her, because i have lost my confidence from a riding accident [at a hunt on a disrespectful bolter, no mouth or seat -.- i had to bail, lets just say my life flashed before my eyes
she is not a beginners pony,
wow somehow the very important part did not come up grrr!!!
she's unbroken, backed etc she just needs a more experienced rider to get her broken
but hopefully i will get her sent away to the trainer [normaly i would do it but yeh....]
once broken you will have no problem
