Criticism on my GBC sprites?

[Quirby64]

Ummm… This look more like a simple recolor of already existing sprites from Wario instead of something you created yourself.

I didn't' copy/paste/recolor these. I made it custom, and the only thing close to that would be using a reference image.
And also -- The original took up the entire of the GBA's screen, & this does the size of a GBCs.
