Still life drawing

Hello hive. It has been awhile I posted here because of my school exam the stress was much more than before.

Here is my one of my still life drawing I drew few years ago a composition of traditional baskets and calabash.

I face a lot of challenges when make this drawing, challenge like shading,and speed,that I don't really know how to shade and working with time is so difficult for me then .But I was able to achieve this in seven hours.
