Nice smile. The lighting is good. What detracts for me is the busy pattern on her sweater. Maybe if you did it in black and white there wouldn't be so many color variations. You could crop out part of it and her hair and it'd still have a nice feel to it.
Attractive model, but the photo is somewhat off topic, "Use cheese as the subject of your photo to make your audience smile." Too bad, the photo deserves a higher score than it probably will get.
One of the better entries in it's class, but not a really originial idea, nor is it as strongly linked to the challenge as those that really had cheese in them.
I hate to be playing English teacher here or come off as a DNMC critic, especially that English is NOT my native language but dissecting the description makes it pretty clear:
USE CHEESE as the SUBJECT of your photo to make YOUR AUDIENCE SMILE.
Based on the capitalized letters I had the following expectations in this challenge:
1. There would be cheese (even if implied) in the photo (Cheddar, Swiss, Gouda...etc). This cheese would be the SUBJECT of the photo. (Subject - Synonyms: matter, topic, theme. These nouns denote the principal idea or point of a speech, a piece of writing, or an artistic work.)
2. This is open to discussion but by Audience I would assume either the voters, or, someone in the photo looking at cheese
3. the photo would be somewhat funny as to make me smile.
After reviewing your photo, I feel it does not meet the challenge either because there is no cheese in the photo or because it's not funny. Or both.
I see no cheese. I'm getting sick of saying this. The challenge stated that you are supposed to incorporate "cheese" as your subject, not that you should take portrait-shot of a smiling person.
