Wow. This is a very good picture for 30 minutes work. It is very detailed. And for a first time full body shot this is wonderful! The only major ache I have with this is her neck... it's... a wee bit long. Other than that, the detail is excellent, it's very good as far as proportions go too. Just work on her neck, and the perspective of her clothing and you'll be all set.
