Hello

I am trying both the software since last week, so for so good to start with my online learning animation, but
I am unable to create complex or advanced time line editing/composing as shown in 'Ending' scene of 'Intro' project. Attached screenshot. 

I am trying to recreate in "new" scene, but cannot get the 'hand' object and animate on the macbook image as in the demo. 
Is anything I am missing, or is there an east way to compose complex timeline sequence?.

Thanks.
Parthib.
