I love minimalism images and this one took by Sarah Dorweiler it's perfect and from her courtesy it's also free under CC0 license. This kind of images are perfect for work spaces with lots of icons. So if you're agree with me and like it, download the image for apply as desktop wallpaper and homescreen phone or maybe for use in other projects that you might have (blog articles, apps, social media, web design projects...).
