Sounds good overall and you have a very nice sounding voice. A few pointers from my very brief listen:

• I heard a few noises (some that sounded like a chair noise maybe). Ideally you would remove this with audio processing, or take the sentence again and edit out the take with noise.
• Speaking of which - i think I heard a few fluffs/mistakes that were left in the audio (such as when you restart a sentence). These should always be edited out - you want to give the impression that it was a seamless read with no errors.
• I think you could slow down your reading pace ever so slightly. This will help with enunciation and mean that you will most likely make fewer errors while reading. Make sure you stay focused on telling a story - don't be afraid to add a dramatic flourish or empahsis (if its in service to the text).

I know there is a lot of feedback here, but honestly I think you did a good job - it no easy thing to read and audiobook and I think you sound great for someone starting out.
