Nice for your first attempt. Handheld or tripod?
They are all a tad soft. Not sure where the issue maybe coming from.
It will depend on the subject concerning light, as Art suggested, they all need a bit of light. The last is easy, if needs a light source from the front. Not very strong, it should make a thin highlight in the dark area in front.
The egg and the jaw looks to be flat, not enough contrast perhaps, or under exposed.
For the honey, my first attempt to change it would be to put a light in front, like the last.
Photography: 100 percent art, 100 percent technical. It takes a photographer to blend them into an image.
Film: That tangible image that you can see and hold.
