Pixel art attempt (Patreon)

Since all of my current projects are waiting for art, I've decided to try my hand at pixel art. And this is the result. It's intended for one of my projects that's named "Flatformer". It's a platformer with a completely flat stage.
Of course I'm a complete newbie when it comes to creating art and it will take a while before I create anything good, but feel free to use it for your game if you want. (The correct sized file is in the attachments)
