well, got a load of studio images, and to me they look quite good and i'm quite pleased. But I've got a feeling that they won't be classed as good enough. I know I need a lot more studio time as practice makes "perfect", it's just tricky to get the studio booked, model sorted, the hasselblad (and everything working) and time from work all at the same time. Studio work is a lot more time management, planning etc compared to our 'street photography'.
But then again lighting is a very personal subject and one persons preference will not always be to the majorities taste.
