its actually not bad. much better then the line animation i did for my first animation. in future, if you wanted to make it better i would add the wave effect. thats basically the only advice i have other then lip sync with the phone call.
I can see that you read some tutorials or watched some b4 u published your 1st animation. Aka the clouds moving, digging hole.
Good job and keep them coming.
This is one i made the 1st week i got AS, i do not call it my 1st animation. It was made b4 i read the help section tutorials. I didn't know what binding points were or much of any thing.
