I can't get this sprite fixed, been working on it for awhile, always has some issues I'd love to get fixed.
Since I'm not really sure what I'm doing I'd rather post it here and get some critiques/edits from more experienced pixel artists. Thanks a lot, any critique/edit is appreciated.

1st attempt:

My friend said the head is too big and it looks weird, it's meant to be chibi though but I did another edit..
2nd attempt:

This one is apparently looking like alien

Both have some body issues, and I'm not sure if angle is proper isometric
Didn't use any references..
