He's not the most manly guy out there, but he's still mature and indeed a teen/young adult. His attire consists of a red hoodie, blue jeans, dark red sneakers, and a white t shirt under the hoodie. He's a rather peppy guy. You can be creative with the pose, but just know he's not going to be angry or sad.
If ya need any more info, just ask!
Thanks in advance~
