Well there's definitely a hint of Cindy Sherman here Susan, the fun is self-evident. You've captured the spirit of her work in the awkwardness of that 'moment' in the smile and the natural unpreparedness of a 'selfie' meant to be a reflection of someone other than yourself. Even down to the lighting reflected in the glasses and lips you've nailed it, normally such highlights would be less than desirable but in the context of the challenge they are the icing on the cake!
this capture the spirit of cindy sherman well, taking on a character completely, becoming awkward with that character, and then taking the photo. well done
To me this is a little too straightforward of a portrait to be in the style of Cindy. I see her images as more quirky and with many of them having a a dark side to them. This is does have some quirkiness but not the dark side.
