Oh I love to hear all of your interpretations!
Trier - I'm the one who's dense. I see the black stick figure now, but I didn't see it while painting it. Especially since I actually painted it the other way around, that is, upside down. After I finished it I tried it all 4 ways and liked this way the best.
EJH - as to migration, how interesting. I thought of it as a pathway that someone or somethings were following, so I guess that could very well be a migration.
Nu - Yes, this one is way outside the box for me, but I had fun doing it. I have some new bar scenes but I'm not sure how cool they are. Thanks for the kind words.
