Woah, this is another wonderfully done picture. I guess I didn't like it as much as the coal one because it isn't as personal to you. It's still great that you drew something from your childhood. I love how organized everything looks. It's great to see how symmetrical you made everything. You even chose a cool kind of paper to draw it on.
I used to go to Philadelphia back when I lived in Pennsylvania. Now that I've lived in Florida for ten years, it seems like such a long time ago. It probably would look better in color. I'm just glad you're paying tribute to your parents. Rock on with your tributes, man!
