This was a good submission. Not a great one, but good.
You took the time to create unique and (relatively) detailed character models, and there's nothing in there I would consider an animation mistake. I liked the visual references and jokes, and the story was told in a fun and entertaining way.
My main criticism for you is that you have not improved very much stylistically in 5 years of animating. Your humor is fine, your storytelling structure is fine. The quality of the audio is quite excellent, actually.
I see that you're trying to hand-draw more scenes now, and trying to rely less on stock images/irl pictures imported into the scene. I really commend you for that! With that in mind, I would recommend that you take some time away from the brewstew series and try to push your boundaries and see how high you can raise the bar for yourself.
I would say you are an accomplished animator. And, I see even greater potential in you from the work you have submitted to the site. With that being said, I want to recommend you try checking out some tutorials on drawing backgrounds, try out some drastically different styles of animation, challenge yourself to make something you didn't think you could, even if it looks bad. Right now you're making things within a limited scope, and you're doing well. I believe you could find great success and satisfaction in pushing yourself further than this series has brought you so far.
