Nice recolors (tho I'm not very fond of them).
But I agree with Gonken, it's not really MC style, so here are some tips

1. Remove the shiny parts, MC sprites don't really look like they where covered in oil.
2. GB Ganon's sprite looks like it's looking directly at the screen, normal MC sprites aren't.
I added a file bellow so you can guide yourself, hope it helps.
P.S. DAMN! Leduardo that's amazing!
