Simplifying form is one of the core skills of painting. As children we over-simplify forms, but as adult painters we tend to want to over-complicate them, adding in every little detail.
That's not necessary to convey a realistic impression of an object and in fact a slightly simpler rendering can often be more compelling for the viewer since it leaves room for their minds to fill in the details - to connect the dots. Our brains love that!
