I need advice please

[tancho-koi]

Hi, I am relatively new to making sprites and so use references to create some.
So I made some sprites I plan to use for a (free) game: it's Link. However, I wonder if my sprites look too much like their references. So here are some of the sprites I made:

I used pokemon sprites and minish cap sprites as references, is it obvious? Do they look more like recolors than originals?
(here are links if you want to compare)
Minish cap sprites
Pokémon sprites

If you find other things that look wrong with him and want to point it out, I'd be glad to hear your critique and advices!
Thank you very much!
