The gray area on his top lip (Basically a mustache or some form of facial hair) only appears when he sings. I don't know if this is an oversight on the idle or because you used the normal Jogg D animation and edited out the beard, forgetting about the top lip's gray discoloration. Likely the latter of the two, but overall pretty cool!
@@AyaanIncredibox Another thing I just noticed is that certain frames have a black lining around (mostly) the top part of the lips. Again, you made everything independently, but these were probably just oversights or errors that somehow made it into the final cut or draft of the animation. The point is, those were things that somehow went past or appeared at some point and were never noticed.
