For an animation made in 24 hours, I appreciate the effort, even if multiple people worked on this. I understand that sprite movies have been frowned upon by some Newgrounds users in the past, but I believe they should have just as much effort as non-sprite movies.
Most people making sprite movies back in the day would've been using pre-made / unedited sprites (either from the original games or fan-made) and even if they did use custom sprites, few actually made every single tiny movement (such as lip syncing, eye rolling, and in this case, biting into a mushroom) pixel-accurate and consistent, ie. actually make the sprites look good.
It definitely helps that you've had plenty of experience with hand-drawn animation before, from what I could find outside of Newgrounds.
