Nice video and good job for your first time out. Once you're comfortable with smooth lines and staying on course, there is a lot of time to be saved with improving your braking. Notice that you spend a lot of time coasting with slow deceleration into corners. It's normal to 'street brake' when you first get started. You can shave a few seconds off your time if you 'track brake'. Either your foot is on the gas or you're 100% on the brakes (with appropriate trail braking and smooth transitions from gas to brake and back). Just something to think about.
Here's a video my friend took from our autoX last weekend. Notice that when I brake for the turn at the end of the straight, she's clamping down hard. Full throttle straight to full braking.
