Drawings Created by Passionate High Schoolers - Not to be Underestimated!

High schoolers who are masters of their art post their work to pixiv under the tag 高校生の本気 (koukousei no honki, lit. “the serious feelings of high schoolers”). The quality is so astounding, you wouldn’t think these creators are in their teens. They’re definitely not to be underestimated!

Do any of the works below stand out? Can you believe they were created by kids aged 15 to 18?!
