The first one kinda shocked me because the face looks so much like mine (minus the peircing)
They look great! They have a great blend between realistic, and non-realistic!
Maybe a tip for the first one: Make the part where the shoulder curves into the arm a bit more angular, not a lot, but juuuust a little.
The hair on the boy looks great, that would be my best attemp with my art style, but I’ll probably release some newer art so I can get some tips from you guys :3
