Still lives sometimes seem a bit outdated...
but I experienced myself that you can learn a lot from looking at a still life:
dimensions, shape, shades, composition etc.
I am therefore organizing a workshop on August, 13 in the evening where we will be looking at a summer fruit still-life and make a painting or drawing of it.
It can be made in so many different styles; impressionistic, loose, precise, in one colour,
it is inspiring, you just need to take the time to do it!
