To be fair, those are the only two things he's made that are longer than like, 30 seconds. I bet when this KD/A video finally releases somewhere far down the line, it too will be peak. He just hasn't actually released much in general, despite being in the 3D smut scene for quite a few years.
In regards to TheCount, I both agree & disagree. Casting Call was a hell of a debut animation, and is still one of my favourites. HOWEVER, in terms of technical skill, I feel that his improvement is quite tangible in the timeline of (Akali anim) > (Neeko anim) > (Seraphine anim) > (Kai'Sa anim) > (Cammy anim). Neeko & Kai'Sa will always be my favourites, but I might be biased because I just really like those characters. Based on the Juno anim and the WIPs from the current Overwatch project, he unfortunately seems to be slipping, or at the very least stagnating.
