Pretty fun! Cool to see how you've evolved, I like this aesthetic you've developed over time. Animation is real solid, consistently high energy and fun. I also dig the more surreal visuals with the weird 3d n everything.
Fred's voice is an improvement for sure, the character in general is more likeable than in the last short you did. Personally I thought he was kinda overly sarcastic and sassy in that short, didn't have much charisma or any real funny element to him, he was just kinda annoying. He works better here where he's still sorta the straight man, but not just making basic snarky remarks all the time.
I will say I'm not a fan of Eric's voice, he barely speaks so it's not really an issue here, but I do think his voice and how he skips certain words is kind of a typical "stupid cartoon voice" if that makes sense. Not really any charisma or charm to it, just sounds like the first thing that came to mind when thinking "stupid voice". I'd try to develop it further.
In terms of humor I do think it's a bit basic, some funny visuals but not a whole lot beyond pretty simple slapstick. Not against slapstick at all, I think a lot of golden age cartoons are great, but I think they also have a lot of other inventive funny ideas and jokes that add to the physical comedy, there was a bit of that here but not a whole lot. Would be a good idea to play up the more surreal elements going forward, I think that's where the creativity of the series shines the most.
Pretty good first ep, you got solid groundwork to really push yourself to do more out there stuff, keep at it Trusty!
