Does he look "too weird" (he's supposed to have a "weird" face expression) or too old for a 21yo?
I’m creating this character for a D&D campaign. To give you a better idea of what I have in mind for his personality: he has a drastically shifting personality—part of the time he has this constant smile, speaks in catchphrases, and easily makes situations uncomfortable because he doesn’t express himself very well. But the rest of the time, he comes across as the complete opposite and becomes very aggressive, though I’m not sure if that makes a difference on the context for this drawing.
So, that's why I want to know: Does he look “too weird”? Also, I’m unsure what to do about his facial features, because I want him to be smiling, but I still want him to have big eyes, and I want to make sure he looks like he’s 21.
