Just be careful and read the fine print…
I was offered a lot of things like this when an animation of mine was featured on youtube.
It looks like a standard agreement that they own your work and can cut in it like they want to… well, just a heads up!
Your animation is very well made!!
I must admit to be on the side of the argument where it doesn’t really do anything for me to see buzz lightyear anymore. That said, your technique in all areas is great! I especially like how nicely, and with great detail, you have animated him.
