Add color or texture with layer masks.
If you’ve created each petal on a separate layer in Adobe Fresco, you can also use layer masks and brushes to add shading or texture that adheres to the lines of your petals. Alternatively, you can use hatch marks with the Pencil tool to shade. “Think about what parts are concave and what parts are convex on each rose petal,” says illustrator and comic artist Jonathan Case. “You’re going to shade the outer petals almost like you would a sphere, depending on where the light is hitting. Where each petal bends is likely going to be your darkest shadow.”
Practice makes perfectly imperfect.
Following a drawing tutorial online to draw a rose step by step is only one aspect of learning to draw roses. Practice different techniques on your own, and don’t get caught up in every detail. “Don’t try to get every single piece exactly right,” warns illustrator and drawing instructor Lucas Elliott. “It’s more about the idea of what the flower looks like and looking at the composition of the whole.” No perfect rose exists in nature — each one is different — so quirks in illustrated roses can enhance their realism.
Sketch yourself a dozen roses.
“If you’re having trouble, draw it again and again. Fill a page with roses. Fill a sketchbook with roses,” says Elliott. “One of the best things that I've found for my students is gesture drawing where you quickly draw the essence of the object. If you draw it quickly, in 30 seconds to a few minutes, it forces you to consider what’s important, and you start to understand the shape of the rose.”
