I am looking at it now. One thing of importance is to never save your pixel art as a .jpeg or .jpg
Jpeg is not a lossless format and truly destroys your work by adding artifacts. you should save them in .bmp, .png, or gif.
I believe the site prefers that you post in .png

Anyways, I will have to zoom in on your sprite... but at first glance it does look better. It's "neater"/"cleaner" (don't know how else to explain it). Although your first one is more of a freeform sketch and "loose", this version looks more like a game sprite and it will be easier to animate and draw at different angles.
I'll post more when I am done zooming in on it.

As I suspected the .jpg format artifact(ed) your sprite to heck. So please post a clean version of it. Hopefully you have an unartifacted save in either .bmp or .png if not you will need to redo the pixel work to fix this one, or start again.

Quote* Only publish .GIF or .PNG images here. .BMP is too bloated and .JPG's have severe artifacting in most cases.
