Is it wrong or right?

I tried it and there was nothing wrong  , I really liked your problem solving but I was already satisfied with the one from before so it stays like this. I am a beginner in this sprite but I can improve with time. 

Well that's no good. Beginner or not, make effort with the suggestions people give you when they critique your work.

Like so:

The back looks weird. If this is supposed to be Super Mario World style (not that it's consistent, but I digress), there are already two really good examples officially already that you can reference.
