Not bad at all! Here are my thoughts: The jokes were all pretty funny. The timing between the two characters was on point. You did say this is your first complete flash animation, so I don't feel like there's any need to be harsh in reviewing that area. I do think it looks pretty good for your first, however!

My only criticism is one that may only bother me. I felt like Raleigh holding the guitar the whole time was a bit awkward because it seemed like he was going to strum it or something between the jokes. It might've filled in some of the "dead air" since the only audio was the sounds of the bayou and their dialogue for the most part. The song at the end that they performed saved it though. Just as it starts to feel a little dry, it changes direction and gets funky as hell.

I might sound a little negative, but I honestly loved it. It reminded me of my out-of-touch family members who use their index fingers to make phone calls on their smart phones. Keep it up!
