State of my art

So it's time for the annual State of the Art Gallery spring photo show, and I'm thinking of submitting this. Basically, I cleaned up a messy home dev shot I took about a year ago (original here), flipped it and stacked it up. Yay or nay?

 

I'm allowed to submit up to two. I'll paste the other contender below.

 

Any thoughts or other suggestions? It can be anything, going back two years, and I'm incredibly indecisive. Help!
