I think it sounds ok. One thing maybe to try tapering out with your volume. I like to put a few descending yelps in the sequence at the end. I also think that moving your whole jaw while keeping your lips relaxed or calling from the side with a loose cheek helps make it sound more realistic. I try not to sound too monotone....good clean yelp ...a few with heavy rasp in the sequence...if I do 5-6 yelps the next time maybe 2-3. Just an opinion.
