Overall, you seem to have done pretty well... The audio was fairly sync'ed up with the visual for a 'best effect', and for the most part, the use of 'jiggly lines' seemed to work... for the most part.
There were a few spots that the 'jiggly lines' were a bit much, or even distracting. The best example here was the candle, everything jiggled, which seemed more like a frozen frame of a candle just being shaken on the screen, where using the internal software to 'stick' the candle and let the flame jiggle on its own might have been better for your cause.
You might also seriously consider studying a little more one winged creatures in general and flight. You do seem to grasp (at least with the dragonfly) the 'flight flap' motion and its archetypical figure-8 form, so maybe you might just want to sit and study the visuals of its mechanics from one species to another in slow motion. I think it can still be googled under 'ornithology' and/or 'the flight flap'...
I can definitely appreciate the hand-drawn effects and the extra efforts for that purpose alone, so I believe you really have something here. I hope this helps for future endeavors as you tease out more of the style and develop it further. Looking forward to more... Good job.
