New Super Mario Bros. Goomba

There's some improvement, Koreo! You've almost fixed the shading.
Don't concentrate too much on one frame when you do animations, just saying this in case you do on the most recent update.
I think your sprite still looks too similar to the SMAS goomba, so I made an edit which looks a bit more like a NSMB one:

As you can notice, it is just about changing the shape of the eyes, adding a mouth and some teeth, nothing very hard!
As for the animation itself... look very carefully at how the eyes move on the NSMB goomba. Look at how the goomba's outline changes; the reason why you can't animate him properly is because you cannot visualise and successfully draw the volume the NSMB goomba is suggesting in the animation.
Use the animator program I linked to: create an animation with the NSMB goombas, then with yours, then try and understand where (which frame or frames) has/have got mistakes on it. Just keep looking at the NSMB animation play, it really does help.
Finish this goomba animation, you can do it.
