This is extremely atmospheric with all that wonderful filtered ceiling light and could easily be mistaken for a market scene in Morocco. It has great lighting, wonderful content with all that human endeavour and detail, and perfect exposure.
Even the overall greenish-blue tones work well. If I had to suggest improvement, it would be in capturing more of people's faces, for example, we can't see the face of the woman in the bottom-left of the frame. However, this is still a great documentary image of human industry. Well done,
Saima's Tip: When shooting indoor scenes with unfamiliar lighting sources, it is worth checking out the white balance options for the most appealing colour and ambience.
