I tried applying this technique I got from Mark Brooks where you use Pale Heath(V000 for Copics) as undertone before applying the skin color. it started weird and purpl-ish but after applying the skin tone, I was pretty satisfied with the result
Not really an original idea it turns out but I wanted to practice negative space..I searched for references and found an even more awesome version by @dimaiv_nov on twitter. I didn't want to back out on my initial idea though and just wanted to explore.
