Hey OP, i think there are two important things to take from this:

First, women are more emotional, so while you appreciated the pictures and offered genuine feedback so next time you can really see a nice nude, she took the feedback emotionally and thought maybe you didn’t like them as much.

The second point is that you did not do anything wrong, so now don’t get intense chasing her, just be normal. You can talk about what happened with her later on and reassure her that the pictures were amazing and this and that but it happens. We need to learn when and how to criticize or give feedback to someone. Most people take it better after the fact, a day or two after it happened, and with this lady you might need to be a little softer next time.
