Hi there!
I can definitely help you with Pixel art for your game. I am currently also designing a pixel art game part time in Unity, so I know how to import and create animations, blend trees, etc. I have done many pixel art walk cycles and custom character designs, so I will definitely be able to work with you to create something special.
I mainly use Aseprite or Photoshop, depending on the requirements.
You can view some of my pixel art on my freelancer portfolio here:

I am an avid gamer as well, and I love pixel art games like Celeste, Graveyard Keeper, Owlboy, Stardew Valley, Enter The Gungeon, and many more.
I am really looking forward to working with you!
