HE'S DOING PERVY NSFW ART, BRO!! The animation is great! I can tell you've practiced for many, many, many years to hone your craft to this point. It's fluid and the characters are incredibly consistently drawn, even frame by frame. All your animations are genuinely some of the best i've seen on this website actually. It genuinely sucks that I feel compelled to give 2.5 stars cause it feels like an insult to the effort put in drawing it. However though... your voice acting, the delivery of your jokes, the characters being so unfitting for their role, it all gives me such a strange sense of discomfort that it was hard to find the words for it at first.
Your motivation/goal for this is hard to understand. Initially it seems like you're defending NSFW artists because they too are artists just like yourself. Then, you turn it around making it look like NSFW artists have no backbone and are mostly just doing it for the money, leading into some weird Ed Edd and Eddy skit of them trying to cope with the fact they're not used to the medium. Theres no buildup for them getting into it either, they just immediately book it into studying what makes people sexy. Initially in the animation they seem to be well aware drawing NSFW has its own challenges, quickly changing their tune to praise in the silly sexy way you'd expect from a twist like that. But then they completely forget, the tune of the plot shifting to 'ohohoho... nsfw artists ARE different actually. they're in a whole other LEAGUE!'. It's inconsistencies like this that throw off myself and other people when trying to understand whats going on. The brain likes a good smooth ride through a story.
Next i'm gonna be super blunt with, the voice acting feels so forced that it was like you held YOURSELF at gunpoint to do it, any jokes being said already overshadowed by how distracting the enunciations for them were. That may be unfair to you as you can't help how you sound nor is hiring voice actors cheap, but the main issue is that you can tell it's just you doing the bulk of it. You don't have to have professional voice actors to simulate a conversation between people. The quality of the art contrasting with the amateurness of the voice acting feels like you just gave up halfway through the project, not even bothering to ask some friends to help you. I guess a better way of explaining it would be that you can tell right off the bat it's a simulated conversation with no outside input, automatically leading people to be less understanding of whatever you're trying to say.
What contributes to making me uncomfortable the most here though was that you made these childish characters with small, childlike features engage in this subject matter in the first place. Even the dog who was 'in the right' was drawing on the floor like a nonverbal child filling in a crayon coloring sheet. I get that some artists make themselves look intentionally childish because its funny, but the combination of everything makes this feel like something a kid or teen would make to frantically prove how they're right and how everyone else is wrong. Maybe thats why it's exaggerated, I don't know. But it looks very weird on you to do this when the same humor could be achieved with the same characters looking like actual adults. A child looking childish isn't funny but an adult looking childish IS funny.
You're a very skilled individual and while you can't be perfect at everything I think you could do a lot better. Storytelling in a compelling manner is really hard, especially for short animations. Things get easily overlooked and by the end you just want to be done with the supposed side project, it's all understandable. Next time however, make sure to plan the pacing out more thouroughly, even the parts you think could be boring. It really matters for short skits like this. The less time you have, the harder it gets to say the idea.
