Here's my work to Lemonade Illustration Agency for Scholastic "Science World" magazine. There was article about drones, quadcopters and similar flying devices. Their usage in modern cities and interaction with people was main point for illustration.
I used Adobe Illustrator for rendering artwork from pen sketch.
Here are some zoomed parts.
For drafts I used ballpen and some markers for shading. Real tools make things easier and making sketches fast=)
Some separate drafts of drones and colored sketches in Photoshop.
And here's final layout in magazine.
Thanks for watching!
