Hi, my name is Wahyu and what I do is I can manipulate an object called pixel and arranged them into small graphics what we called pixel art. Those graphics could be a simple sprite, animated sprite, and a tileset. Then you can use those graphics for your purpose, like printing then hanging on your wall, or you could use them to build your game, the choice is yours.
In case you are wondering about my work, you could find some of them here:

I think that's all
Thanks and have a nice day!.
