A little frog

First post!!!
Aahh I love vacations... plenty of spare time for drawings :)

Please find below an animated line test. This little frog will be part of the opening sequence of Post Sciptum's animated short (get more info here).

The sequence will start in the jungle. The viewer will follow the adventurous flight of a dragonfly through the vegetation, avoiding some dangers (the frog for instance), until reaching a clearer space where we discover we are in a tropical island.
From the beach, few cars and tanks move towards the camera. The dragonfly hits the windscreen of the first car, where an Orson Welles looksalike character laughs and fires his gun on the air.
The camera still goes on and focuses on the sky where an helicopter heads towards the small rocky island few miles from the beach.

It will be my first challenging multipane animation so I hope it will end up ok.
I will post all the progession steps of this here (among other stuff) in order to share the creative process... but most of all, to get your feedback :)
