I'm a real noob to pixel art, moreover I started the contest very late,so I wanted to do something very  simple : I made some limestone wall tiles.

The proportions are a bit odd but I think it's still cool If you want to make some ancient ruins of labyrinth ...

All the tiles are made in ASEPRITE (aseprite.org) with LPC's palette. I added a .xcf source but  it is basically the same as the PNG one with one tile by layer.

I hope You will like it !
