Help me with my SMW sprites

[Torres.]

I want to do a Whacka sprite sheet in Super Mario World style, but I can not get it to look that, like, old school. I used the super mario world tut. It helped me, I think I did how they said you should. But it doesnt look like those old sprites. The pallette is right, I got it from the tut. I also dont know where the light comes from (top right) or (directly above) so I did both.

The goomba and buzzy beetle are examples of the real style.
