I really like the piece you posted. The details are esquisite, and you tell a lot about Tilda through the world you've created for her. For one, I know she's in a steampunk environment because of her dress and the environment. Second, I know she's not afraid to do what needs to be done. Third, since she's rescued a dog, Tilda has my immediate affection (I'm SUCH a dog person! lol)
I really don't have anything to critique in this section, which is good, right? lol I can't wait to see what you come up with for the assignment in Week 4!
