Montage video

I have made a new video but this time around it a montage video. I didn't know where to post since I can't post this one on the animation thread.
I wonder what you think of my art, did you like them? What can I do to improve? the montage is showing how each of my art got better through time.

Nice stuff dude! I am not an artist so I can't really offer any tips but I do know it's important to practice every day (if you can) so that's what I will say to do

but yeah good stuff you got going there!

It was so cute~

I'm sorry, as I also do not have much criticism to give. Though, I did notice in some of your custom(?) sprites or pixel art, the lighting source seemed off, or non-existent. I think that would be something good to study and research to improve your work.
