I personally like more highlights with stronger shadows. And if thats kinda a vibe you want to go for you can brighten and darken stuff. And for like breaking it down you have a really solid base to work off of in shapes and how the light would hit em. You can add more on where the light would be coming from. Adding big blobby shape for where the light hit can also help as you can trim it and make it more accurate to the hair strands. This is an incredible artwork so well done (especially for like just winding down like WOW) also sorry if this wasnt helpful <3 | Artwod Feedback
