I see youve been practicing with this type of shot looking at your recent uploads.
This is a type of still life photography. You are right when you say a photographer makes an image, rather than takes one, and whats meant by that also includes using light, composition, mood, timing to create something that is appealing. Its not necessarily that one actually builds an image, BUT, as I mentioned, still life is one area where this is exactly what you do.
Lets start with how the image looks as far as exposure is concerned. To me, its underexposed. One clue is that Polo Mint, - it should be white, so some issue with exposure and white balance. Did you use a tripod? How is it lit? All of the previous sweet shots are underexposed also. Whats common in your settings and approach?
Look at the depth of field, - the area thats in focus, which affects the extent to which the sweets are sharp from front to back. Its very narrow, and doesnt encompass all of the sweets. That can be fine if you want only a small part of the sweets to be in focus.
Composition and content, - what is striking is that ref background; its overpowering the shot. Red is a colour that really attracts the eye (not just bulls!), and using someting white, or black would work better to focus the eye on the subject. Its very different, the collection of sweets and the pepper, but using something liie sewwts can give you a wide range of options, depending on how they are arranged.
So, I have uploaded one mod that shows the image with exposure increased, and the Polo is closer to white; and a second mod where Ive indicated the extent of the depth of field. Its reads such that the bottom line is closer to the camera, the upper line further away. You can see its very narrow.
How do you address these two issue when shooting? First, I see you have used spot metering; until you become very familiar with spot, and which spot you need to meter from, stay with the basic metering mode. (Did you also use spot for the previous shots?) Basic/standard metering will work for most situations. A spot reading will often need to be corrected.
Next, the aperture is what determines the depth of field. and it is also dependent on the focal length of the lens; for this shot, using f/11 would provide greater depth, as would moving the camera a little further away from the subjects. Or, if you wanted a sifter shot with less in focus, use f/2.8 if its available.
Take a look at the mods. Try a different background, use the standard metering mode and a smaller aperture (bigger number). Use a tripod, - you dont say if you have done that here, but if you use a tripod, you dont need ISO 800, and you can work with a slower shutter speed.
Hope this gives you something to consider for the next shot.
