your graphic style is great, and the idea is good. But i think that the reading flow turns a bit broken by the necessity of keeping the cursor on the frame that you wanna see the animation. I think that a direct flow, like a motion comic, or everytime that you click, pops up an a frame with the whole animation would be better. But it's a promising work, congratulations on doing and keeping this project on!
this is super awesome, i love all the birds, but i think you lose the sense of sequence when some of the panals return to the original image eg. in the last page, you would get a real sense of birds flying off if they lest the middle panel and stayed gone when you roll over to the last one, instead of returning to the start image.
