Much better than a lot of other themes, animated or not! Congrats! :)
I like that this theme, unlike many others, doesn't disturb tabs titles, buttons, bookmarks bar visibility, the color chosen is in between the scale, moderate, not exactly great looking but balanced and being so it's more useful and fit. Overall, colors are well chosen, nice, dark theme.
Also, you took care of the sidebar, which many people forget to do. Good job!
The problem with animated themes, though, is that they use CPU and consume much more electricity WATTS just by being active! :|
