These are few examples:
I'm animating with the soundtrack uploaded to the timeline. And here also music suggested the sudden change of Ivan's body language where all of a sudden the bird forgets his confusions and lets loose towards what he's attracted to.
the bird reaches the window and inspects the new. Again he is only assured he wants to reach outside, but has to come up with the way to overcome the first obsticle - shut window. He comes up with an idea after he sees the little lock.
These two videos were yesterday's and today's animating. I'm taking the time there. But these scenes are a great warm up before the much more complex animating still waiting ahead.
