So, one of the first things you learn about pixel art when talking about tiles is breaking the tile. This general means that you place pixels on your turf (whatever size it may be) to carry onto the next tile. (Unless I'm completely wrong with that assumption) This partially hides the fact that you are using a tile over and over again, but how exactly does this apply to sand?
I did a sand tile based off of something Grimsane did a while ago:
Which makes it strange though, is that waves in the sand are more defined than a blade of grass. So what exactly do we do in situations like these? Would a simple solution is make the wave a bigger (64x32) and simply do several different waves and make them overlays to be placed on the sand?
