I would suggest that you think more about the styling and content of an image - variations on the "who would use this" and "what story or setting is the image showing" questions. There are also a couple of food items with white balance that's off and it makes the food look really unpleasant - food images should make you want to reach out and start eating the food. This bread is an example

As examples of odd styling - an odd mish-mash of costume jewelry and a safety pin will limit who can use it - fewer items and a better setting would work for more buyers; why are Cheerios being poured out of a water glass?; if the story is saving egg shells (to use in the garden), perhaps a setting that suggests what they'll be used for?; these wrapped boxes look industrial, not like gift boxes, not really sure what a buyer could do with this, especially as it has a background (versus isolated)

Also watch your keywords - on the jewelry tray image you have girl, woman, wedding, pirate, dream, wooden - none of these are in the image; the yellow slice of bread has toast, bakery, diet - it's not showing a bakery and the bread isn't toasted. 

Good luck

Thank you very much.

Hello microstock community,

I started about 1 year ago in the microstock business. I sold 81 just in Shutterstock, earned about 30 dollars.

Now I have only 84 photo in my portfolio. I need you to advice that I can improve it.
