Animation is one of the most timeconsuming processes you can devote urself to to be creative.
The only thing he doesnt do is the voiceacting, everything else, the models, the sounds and background noise, the animation of course and the editing etc, all done by him, its completely stupid. Making a 10min vid with voiceacting and facial animations between the porn shots can take months. if you look at the gwen vid, the scope is for a much longer vid, which will likely never really return in a way that is satisfying enough to justify dropping months of shorter clips for it.
If you want to criticize him for it, dont talk down on the work and talk down on the stupidity to not outsource some of the work and actually take healthbreaks to be able to provide for those paying under the subscription model he goes by that makes all of it possible in the first place.
