How can I make it better on these "uneven jumps" ? I suspect you are talking about the glasses.
very sloppy, lots of jaggies. some lines differ in width between 1 and 2 pixels, lots of uneven jumps in the length of line segments. bit too sketchy for the gallery, I suspect
tbh i didn't know there were glasses, i can't really tell what anything is. check out the 'jaggies' section of the pixel art tutorial, might be of some help.
