Lettercase Syncing Animation

The animation is in no way indicative of the speed of syncing, but I wanted to illustrate the percentage over time; the window fades in (illustrated in the attachment), does its duty, then subtly fades out. Also, ignore the shadow changes – just imperfect screenshotting. And hopefully, it's obvious the real deal will be smoother – I just made a gif of random %'s, not the entire process.

So with that in mind – any feedback? I like the simplicity, and I think the animation adds a little extra visual feedback of how far along you are in the process.
