What you'll need
Martin used a reference photo to begin her illustration. Feel free to use the image in the PSD she provided, or import your own.
Before starting, Martin tapped the + icon to create a new layer. Then she enabled the ruler and chose the Conte Crayon brush from the Dry Media category. As she drew from the photo to the canvas, the brush snapped to the ruler creating the straight lines she would use as guides. Martin continued to use the same brush as she drew the sketch on its own layer. She provided her sketch as a hidden layer in the PSD. If you’d like to use it, tap the sketch layer then tap the eye icon to show it.
To add flair to the portrait, Martin exaggerated parts of the drawing. She chose the Lasso tool, drew a selection around the foot, tapped Transform from the bottom menu, then used the corner handles to resize the selection. She tapped Done and Deselect when finished. Martin used this technique to make the head smaller.
Once Martin was ready to apply texture and color, she added a new layer to add color. She used the Eyedropper to select colors from the photo and drew with the Conte Crayon brush from the Dry Media category.
When she finished the illustration, Martin selected the Transform tool and dragged the illustration over the original photo.
To create a composition that blended the illustration with the photo, Martin chose Create empty mask from the layer options. Then she painted with a black brush on the mask to hide portions of the illustration and reveal the photo underneath.
