Love it
You got me, it's my favorite Beatles song too.
I think the best points in this flash are the visuals idea: the eclipse, the melting ice, the reflexion in sunglasses, etc. You had nice "camera-effects" and interesting perspectives. The cheerful feeling, the soothing warmth of the sun is clearly felt through your movie, at least for me.
I think the only downside are the drawings. It's not that they are bad... okay, it seemed a bit choppy sometimes and I feel that it drag down a little bit the overall feeling, but what annoyed me with the drawings was that they were kinda cheesy sometimes, like the baby things, the couple looking at the sunset. Mainly the still images. The animated sections with effects were really well done!
I really liked it, keep doing awesome flashes on awesome music!
