Minimal Woodcut Illustration N°1 - Charles Darwin

I've been trying to draw simplified portraits in woodcut scratchboard style, I found it really hard to bring down the amount of details depicted and still be able to portray the subject to be recognizable, this is the first in a series I will be doing, so let me know what you think, and If you're an experienced illustrator in this style, I would really appreciate any tips to simplify this even more, thanks 😎
