One of the ways that I enhance my drawings is by adding colors and textures in photoshop. I scan the image into my computer and then add some new elements.
Here is my daisies that I drew. I added some unusual colors for the petals and wanted the background to have some pop as well.
So, like a recipe I added a few things, a yellow gradient background, a basket weave pattern and a iron gate.
And the finished result. I like the contrast between the flowers and the background and I the repeated pattern of lines with the gate and the background.
