That's fine, and maybe they will do it even more justice. It's art, and if these small assets are where your game shines, then it's probably better anyway to do all these assets from scratch. But if you wanna put your time and creativity somewhere else, you are able to efficiently complete those tasks and get to the part that you feel is most important for you game. And you will have more time to invest. And I think that makes art design and game development more fun.
