Hmm, I guess this is a dupe. You all got ripped off!
Not necessarily! There's enough differences to make it worth being a different piece; slight x-ray elements, slower animation speed, and the obvious difference between sketch and colored-in. Frankly, it's just nice to have something new to look at each day - I think it was a good call on the automatic updates.
Nope, no dupe - one's colored, much like your pleasure tf animation. Both of which are awesome.
