First time drawing a female head.
Tried to use more construction lines like the other anon mentioned last thread but my proportions are still off and my drawing does not resemble the ref.

I struggle mainly with the eyes, and although I can pinpoint flaws once the drawing is more or less done, I am still fucking up the positioning of features. Nose is too long and mouth should be more separate from it. What fucks me up the most tho: I started with the right eye which is too far apart and all plumbing lines drag that error (mouth too wide). Is there any way to correct that in the beginning or should I just train my eye by drawing more? Also how's the overall head shape and the shadowing? Help lads I just want not to suck
