I wanted to complete something to my previous post regarding the fashion illustration I did. Take a look at the crops below. They are all details of the illustration below and each of them can be printed on large formats and considered abstract art. They can be paintings too.
When every part of your fashion illustration is as interesting as the image itself, your painting is a success. The images that compose your illustration should be entertaining too, they have to say something, they have to live.
Try it yourself! Make a rectangle shape in the middle of a white page and start moving it along the illustration you finished. Check if there are corners or areas that are not as interesting as the whole itself and improve your skills for the next illustration.
