Possible pellicle forming on partially-wild brew?

Here are a couple photos of a brew I put together, inspired by some people who mimicked ancient Sumerian beers. Mine used a combination of commercial yeast (Wyeast 1272) and the yeast and other bugs naturally occurring on dates. The main fermentation finished up a few weeks ago, and I noticed it's starting to form little bubbles on the surface. Is this a pellicle in its infancy? I've never brewed with anything other than commercial sacc strains before, so I don't know what I'm looking at.

First, the residue from the krausen looks a little unusual:


Then, here's the surface of the beer right now:

Looks perfectly normal to me. You'll know a pellicle when you see one. They look gross. That looks like some CO2 bubbles.

Well the reason I thought it was strange is there were no bubbles a few days ago -- it had settled down completely -- and then yesterday the surface started getting a real thin film over it, which is now catching bubbles and retaining them.
