Hi! I'm making an asset pack of expressions, with paid and PYWY parts, using a Blender program with variables for eyelash width, eye angle etc. Would it be ok to release eye images with the same dimensions as your eyes (I effectively traced the eyelashes and pupil outline as my base to edit from)? I'd link to your account both for credit and to let people know where they can find full sprites with compatible dimensions. My pack isn't as pretty as yours but offers a wider range of expressions and shapes (including eyebrows and mouths, which I didn't base on yours). If it's not ok I'll just release a more generic "anime" style which won't match your art so closely.
Also: I can make the parts based on your art all PWYW if you are more comfortable with that.
