Draconland

It looks good but the skull would stand out more with a darker background in my opinion. The sprite that is 1st on the left on the 2nd row of the sprite sheet looks very good.

Thanks.

The light gray (white) in background is needed to use on skull, I can set black pixels to hide the white around the object but I'll lost the outline information I like to keep in my sprites.

The sprite you like is the original, others 2 are modifications to fit the technique limitations (16 pixels wide for black pixels, 2 colors limit for each line + background white ).
