The shape of the head looks good but the eyes could still be improved. That downwards indentation seems much too wide, if you could knock half to a third or so off the width that would look a lot better.
I spent an hour or two on photoshop trying to illustrate a vision of what could possibly work with the eyes, but was frustrated as my photoshop skills are too basic and I couldn’t work out how to draw it, so I reverted to paper and pen instead.
Can your program draw parts of circles as well as whole ones? Like the moon being circular, but when drawing a crescent moon the part we see would be made of curves of part of bigger circles which mostly isn’t seen/drawn. Hopefully the rough drawings below will communicate the idea:
The up of both eyes could both be part of a curve from the same circle (which in its entirety would extend much bigger than the head itself). There could be two other part realised circles below this then and both would meet with the slit. Size and positioning of circles could be played around with to whatever works best.
If that's unfeasible or not worth bothering with at this scale another option could be to maybe try diamond shapes (ideally rounded or squared off a little if possible) to the left and right of the top of the slit. Something like the warrior on the right here:

I used to have a Microwave that had a "Chaos Defrost" button. (WTF?!?) I daren't press it, just in case.
