It is hard to say rrostek's works are bad or good....I mean some blender or sfm makers are quite good indeed, such as guiltyk or Vgerotica etc...But, almost all of them are not working animations and videos with monster\inflation\extreme hardcore and brutally fk\ voiced\ game girls and other perverse elements together.
So, yep you are right about that we have only rrostek here to do the job in this area....
However, i think rrostek has his own style or habit on his works, and i feel these works suit my appetite...well, just my personal view...
And i recommend these video makers to others who prefer high quality works:
guiltyk
Vgerotica
thecunt
generalbutch
Nagoonimation
redmoa
jackerman
Bulging-Senpai
f.o.w studio(dead already)
yeero
animopron
darklust
