Good for a first, I thought the using the pipe as a cannon with Yoshi hitting the switch was pretty original. Also, that thwomp hitting the P button was really hard to see, I didn't even notice it my first time watching.
Main thing is that the animation just needs to be a bit smoother, and that just comes with experience. And if you weren't, try using a vcam for zooming in and such. I thought it could be more zoomed in since there's plenty of unused space above the block (for most of the animation anyways).
But yeah, nice for a first~ Much better than mine. lmao
