Your tone is pretty good on your line delivery; just watch out in terms of your pauses, since you want to sound natural when you're delivering the line instead of as if you're reading from a script. As for the singing, you've got a good sense of the rhythm and tone, though there appears to be a bit of audio desync when Big Band comes in with the melody? I assume that's a quirk with Audacity and other recording programs. Pay attention to the rhythm in the scratch as well; the syncopation in the vocals is pretty essential to the characterization of Big Band, as syncopation (basically accents on the up-beats) is an important basic tenet of jazz music. Thank you very much for auditioning!
