I can't really see your second picture, but your first picture looks 3a to me. Your hair is really long (and absolutely gorgeous!) so the curl is probably looser right now than if it were shorter.
Having said that, if you are looking for the best advice about the health of your hair, the curl type doesn't really matter. What you need to know is the other features of your hair, such as porosity. If you search around the forums, you'll find lots of info to guide you in this. Good luck!
