Super Mario Bros custom tileset

[DioShiba]

-His gullet should be reduces by one pixel.
-There is a line going over his eyes

Please tell me what exactly you mean by those

Since I'm feeling somewhat obliged to help, click this link.

Next time please google things you don't know before you ask questions like these, it will save the effort for us to actually explain our points harder than we need to just because you can't understand what we are saying. thanks.

also far as the line going over his eyes I'm going to assume that's a part of the nose, but honestly I think you need to put some selective outlining on the sprite itself for the sake of readability. which would help quite a bit.
