Honestly, the quality has dropped a lot in my opinion.
True.
I was such a huge fan I started supporting his Patreon just after Sensual Adventures 2. Even did the $100 (one month) to get a custom animation one time.
The guy was awesome and actually opened my eyes about the whole fluid simulation thing (read: cumshots).
However after episode 4, the cumshots started becoming quite abysmal. Strange as he was upgrading his gear and techniques, taking on hirees (sub-contractors) to help him get his animations and games out there faster.
I think I've seen all his stuff post episode 4 (I think the last one was episode 9) and still, the cumshots never were as good as episodes 3 & 4.
Shame.
Anyway that's my 2 cents' worth on the subject.
