You don't like to draw but you still would like your storyboard to be visual? I have a few tips that can help you do exactly this.

Use the Innosketch Kit

The Innosketch kit is an illustration set with 460+ ready-made sketch elements that you can combine to create your own sketches. It's totally free to use and I've made all the little doodles myself by hand.

Use the undraw symbols app in Miro

You can use the unDraw Symbols app in Miro to get a selection of illustrations you can drag and drop directly on the storyboard. In fact, the examples of images in this template come from this app.

Use illustrations from the undraw website

If you want even more choices you can go on the unDraw website to find even more illustrations that you can easily adapt to the colours of your brand.

Use animated GIFS from the Giphy website

If you share your storyboard digitally you can even make it animated with animated GIFs. You can find a tone of those on the Giphy website.
