This looks good for a junior. The storytelling / showing us where you went on the chair is really nice!
I would really like to see that level of depth for the messenger bag as well -- it goes from the design brief / goal and then suddenly into the final solution (although the final model looks very legit!). It would be great to see how you got there. Once that is in there, it could probably be as much of a "heavyweight" in your portfolio as the chair.
I think the form / feeling you chose for the incense burner is great!
