Honestly, didn't really like the first one due to it being just a bit weird but that's my opinion and I'm sure people differ from that lol.
The rest were excellent. The flag one could be put in a flag shop with all the same hats but with different flags/names on each one. That would be really cool.
The blue duck one was my favourite. It looked amazing and I actually thought at first if that was in a shop in era. That's how realistic an close it is from actual admin graphics.

I think your work is great as always and you obviously have some skill in the pixel graphics sector. Keep up the good work and you never now, you could be a future admin lol ;)

+rep. Keep up the good work
