Do not you like relaxed and cosy models that trust the photpgrapher and know what they are doing? There is totally nothing wrong with amateur models, it's just so different. Difference is in the number of shots that needs to be taken where pros or naturals give you a nice pose every second or third shutter click. And as for the amateur beauties you have to guide them quite a bit more you can still achieve unique results.
