Is my character as much of a mess as I think he is??

This is Carl (the name is a work in progress, feel free to suggest like anything else), and I can't tell if he feels like a realistic character. All critiques are welcome, thank you in advance.

(the picture on his profile is rough. The app I was using didn't have a lot of options)

I'll just go throw myself away now adnsdfnaeyrdfblvehf
