Pitch matches the characters age well here, and the more throaty nature of your voice adds to the deliver of the lines. The delivery is well enough, as you do manage to hit the emotional peaks when necessary and make them sound natural with your chosen voice; though you could draw out your words a bit more on the second lines to make them sound a bit more depressed. The more gruff and grizzled tone hits a nice balance with the slightly slower delivery here, which works well enough for your audition and only really falters in the first half of the second line. This is the only part where I feel you need to have a more somber tone to your reading, as the intensity of the other lines work well enough with the character facet you've chosen here.
