First plush vs. latest plush (Luma plushies)

Hello~ !
I made these two with the greaaat tutorial from  ~clearkid.

The left one is my first plush ever, I learned how to sew and practiced on it. The right one is a commission for a friend, and it inaugurated my brand new sewing machine, my dear Singer <3. It's a kind of competition between Hand-sewn and Machine sewn .
I still can't get the eyes sewn in an esthetic way, no matter what I try, it's still a mess of stitchings...
