You can use the standard subject for Still Life drawing, inanimate objects like fruits in a bowl, flowers on vases, food on table, books, drinking glasses etc. It was ancient times.
Why don't we try using pieces of technology for the subject?, Cellphones, tablets, Computers or laptops, etc. Since we are now living in a modern world.
Or try to put Orange and a cigarette together on a table and start drawing it. It's not a good combination but it's cool. Orange symbolizes health and the Cigarette is a deadly symbol for cancer or other lung diseases.
Experiment with other things that looks weird when you put them together, draw it with passion, and it must have symbolism, a deeper explanation, and there must be a meaning for each object.
