Art interest check for my dream collectibles

[King koopa]

Now, before we start, my name is not Bob Ross, so don't expect it to look super real, but don't expect it to look terrible either. I REALLY want these collectibles, especially for my October lineup, so I thought, why not see I anyone would be interested in my art for the collectibles?
Collectibles I need:
Koopa's beautiful blue lineup, almost done! Just need a cool feather

Koopa's puzzling purple and bold black lineup: Almost there! Just need a purple bat potion

, purple star fragment

, wix candy

, and a dark egg

Koopa's forever fall lineup: halfway there! Just need a green feather , red feather

, a famous mushroom

, an apple

, and a November birthstone

Here is my work:

And Katrina as a pirate looking for a pearl. Let me know if you'd be interested in trading, and any and all help getting me towards my lineup goals is very appreciated! Thanks for looking!
