She's probably just a little nervous, since she's still new. Give her a bit of time. I've had mine for almost a year and he still follows me with his eyes.
Also, your parameters seem a bit off. I think the temp should be closer to 75 - 85. And I had shed problems when my humidity was at 60%. Also, you don't want your entire enclosure to be the same temperature. You want a warm spot and a cooler spot. They grow kinda fast, but at a year mine's no where near full grown.
