Awesome work! Though you already mentioned the neck being off, other than that, it looks very close! A quick tip I like to implement is to confirm alignments for major shapes with two different landmarks. For example, instead of only relying on the chin to place in the neck, I would also confirm with a second alignment like the pupil (or the eyebrow corner, too) on the vertical. Hope this helps! Keep up the great work :)

Try looking for natural landmarks that tend to align if it was someone looking directly at you for example ! I think the moment you start seeing an eye and not a shape, is when you need to take a step back (also quite literally, you'll simplify shapes more easily). Since we see people everyday, we interpret it as something we know, but you need to really switch your mind into "simple shapes" mode ! For example, if you squint your eyes, you'll see that the hairline above the forehead is one horizontal line. Don't mind how much time it takes, this is usually how you'll end up rushing and getting into easy mistakes :) Really start from big form into smaller ones, try finding every big one you can before getting into details ! Good job anyway, keep it up :D

You did a great job with the eyes! That was a tricky part for me and you seemed to have captured the positioning on the face really well.

I might add that one broken string flying off on the original drawing. Overall, you did awesome! The textures are really well done.

Great variation! Love how different shapes were used for each one!

I dig the variety. You made a bunch of iterations. Nice work!
