Just my personal opinions :
For the salad, if the egg can show more egg yolk portion will be better to add more color to the dish.
The natural light seem a bit too strong and wash away the color. Might want to bring back some saturation in PP.
For the other dish, the rope and car jack...
Just few points :
1. WB off as mentioned by Nanoo,
2. DOF too shallow. Try not to push aperture to max.
3. There seem to be some focusing issue. Some pictures seem not in focus.
4. Try not to have too much stuffs in the background.
Practice more and you will improve.
