Those are great! They look official. I'm glad that you sprited Sneasler so I don't have to do it. (I hate Sneasler with a passion lol.) Here's the Buzzwole I was working on! It took me waaay too long, this swole lad has a very detailed design. I'm pretty satisfied with it, at least enough to move on to the next sprite!

Also, I have these DS Style Galarian birds in my folder of sprites. I didn't make them, and I can't for the life of me find who did. Anyone recognize these?

Edit: I can't seem to get the images to show up. I uploaded them to Imgur and linked them, not sure why they aren't appearing. I'll just leave the links to the images. 😅
I believe Wolfang/WolfPP made the galarian bird backsprites. The problem is how you got them though, where the last time I contacted him about those sprites, as well as most other sprites like those he made for Gen VIII, he sent me this message:
"Hey! I'd like to use them first in my game and then, release to free use. Also I still need to finish them and looking for someone with blender to help me out, and double check the others gens." -Wolfang
This means sprites like those were meant to be off-limits until the project of his is done. All I am curious is how you got those sprites under Wolf's conditions (I guess if you are a close acquaintance with him).
Here are where the sprites are from, credits to WolfPP:
