These are 3 of Valeria Docampo's works, children's illustrator who i admire. And although she draws illustrations for children, she does it in a very profesional way and in a very personal style. I like her use of line and the use of color. Although the illustrations i chose are monochrome or almost monochrome, she has much more in bright and vivid colors appropriate for kids.

Here I leave her website so you can see the rest of her work
