Old School Breakfast - Bread and Jam

Hey guys,
This is my first project and my first post on Blenderartists.
So I would really like to step my blender’s skills up and for that I think I need yours critiques.
This is a scene of a breakfast in a desert hut where they would have to make the bread and the jam.
I don’t know, I think I could improve the cloth strings in some parts, but other than that I could use your critiques in things that I can’t see or don’t know how…
