What is the subject of this portrait? I'm unsure if it's the birds in the cages, who are quite obscured, or if it's the out of focus lady behind.
So it doesn't work for me in that sense as i don't know what i should be concentrating on.
In a "portrait", I would expect the person to be the strongest element in the image (the biggest, the sharpest, the most detailed). Instead, I'm looking at a bunch of sharply focused red boxes and I can't even tell what is inside of them (other than your title which alludes to the possibility that they might be birds). Meanwhile, the girl on the left is out of focus and is clearly not the "vendor" alluded to by the title, so all that's left is the hand on the right ... ah, that's it, that must be the vendor. But is that all I get for a portrait? A hand?
Wish the focus was actually on the bird vendor as opposed to the cages for the sake of this being a portrait challenge... actual just in general for that matter. The cages aren't very engaging as the bars are too close together to really see much.
