Very pretty! They can change color when stressed. Yours almost had the coloration of a Viper Boa initially. I think any snake that isn't handled sufficiently will be started easily and possibly nippy. Just take her out on a regular basis and she will chill. Looks like she's adapting well. 
Has she eaten for you yet?
