2D designs

I’m creating a personal project, a 2d rpg game style, the theme I spent hours looking at pages and pages of unity looking for resources (Sprite, tiles, weapons, character, etc), the problem is artistic differences, for example Character of the store, but does not match artistically with the mapping, I do not know if I am clear … Is there a pack or some recommendation that can give me to help? (I do not look for free packs)
PS: I DO NOT SPEAK ENGLISH, SORRY!!

This is my go-to for prototyping, they’re all free.
