Not a fan of the colors but he's cute =)
But you'll have to be more precise if you want us to tell you if your chara design is good. Like is it a main character, side character, extra ? What kind of personnality does he have, what's his backstory ? What kind of story is your comic with what kind of tone ? Does he blend well with your overall style (background, other characters etc)
So if your question is "Is this character cute and lovable and do you think he'd work well in a comic ?" Then my answer is yes.
If it is "Is this a good charadesign ?" Then I have no idea =D
