This is absolutely very nitpicky of me and is in no way a major issue of any sort, but in the animation of the Roo, before each movement, the outer outline, including the parts that do not move seems to slightly pulsate as the line gets thicker and turns to its regular thickness again.

My guess is that the line weight at some point during animating slipped to a slightly different value somehow.

I wouldn't necessarily say it's a must-fix, definitely not a high priority one as that's something that might take more effort than it's worth, but I figured it would be good to make sure it is known that it occurs.
