I give you my honest opinion for the only image I see here.
Your image are not lit properly. Look at the brilliance of metal objects, this is not a proper shine. It looks like an image not have a controlled light. Also, your picture is very flat. But not good flat. Shadows are made very badly, like spotlight is over. Like you take a picture at day 13.00 with sunny, outside. The concept can be ok. There are still problems of color and object contrast.
If you want to take pictures of objects outside, my advice is to take pictures in the morning 6.30 - 8.30. The light is very ok. Also you can control the light through a window. Unless you have special equipment.
If you can add here others pictures … ? I can see here only a picture.
I finished the visual arts university (department foto-video).
Good Luck !
