I worry about making critiques because the fact that you are actually producing comics when I am stuck with zilch. So I feel like I need to make disclaimers, like, I really like your comic ... which I do or else I would not have you on my friends list. However, I have to make comments like this.
I have observed that in this journal comic of yours, the characters never open their mouths. Sure, if your characters are toys, that is one thing. Although, you are not really a teddy bear, but an anthropomorphic avatar for yourself. Your wife on the other hand is a human and has no excuse not to open her mouth (unless you have some telepathic abilities going on there). Furthermore, there is rarely any emotion shown on you or your wife's face. It is the same blank look in almost every comic.
You have talent as it comes to coming up with ideas and producing a regular comic with a level of quality. Beyond anything else, I think the facial expressions is the one thing keeping you being a good artist rather than a great one.
