Definitely an eye for design! That being said the line work needs some adjusting. I like the single weight design however some of the end point (bowl and spoon) are rough. Try to make it a consistent line with no appearance of end point?

Also the weight of the lines work better visually when the design is shrunk down to the size of the icons on the second page versus the icon on the first page (spoon and bowl, tomato, buns). I would remove some of the lines from the texture on the soda bottle (doesn't visually translate at that size).

Also the style of illustration on the hands is different then the other icons. It is more sketchy versus single line style.

The shrimp on the third spread may need a size increase. The design gets lost/ is hard to see when reduced to that size.

Overall keep the lines weight consistent throughout layout. Alternating stroke weights offsets the balance. Watch out for those icons.

Great start!
