Not intended as a diptych at first, still unsure. See the single images below in comments (and on their own page).

Let me know which version you like best (if you like them at all)!

[EDIT: Love love love that so many of you are chiming in with what you think! I will reply to all after I finish checking out and commenting on all the wonderful World Photography Day event photos!]
---------------------------------------------------------------------
[MORE EDIT: Here's the current count on your choices between the options of diptych, A or B

Diptych: 8 votes
A (black and white): 1 vote
B (sepia-ish): 2 votes
Can't or won't choose: 8 non-votes

This makes me laugh - apparently a large portion of ipernity users don't like stating a preference for anything! Many people wouldn't even say what photographer they enjoy/admire for World Photography Day - and here, just as many people voted for the diptych as couldn't decide or chose not to even think about it.
The funny part is that one reason I asked for other peoples opinion is because I couldn't pick! So I join that crowd.

My husband, who has a lot of sway with me, voted for B, the sepia-ish version. He is a very decisive person in general. I continue to go back and forth, though I agree with a few people here that B stands well on its own, but that the diptych adds something. I'm going to bring it down to if I decide to show this in print somewhere, looking at prints will make it possible to decide!

Thank to everyone who has voiced their opinion, be it a vote or non-decision just liking the photos.
