Here's the original drawing that I did of 2 love birds. I wanted to do something to the background to make it a little more interesting.
I scanned my drawing into the computer and opened the file in photoshop CS6. I selected the birds and then added a layer with a new black background. The black makes the birds stand out and I liked the way the colors popped.
The next stage involved added some foliage/swirls. I chose another fun color and placed them behind the birds.
I still wanted more of a background - less of a wallpaper look... So I added a gold grid. It reminds me of a birdcage.
The final additions were some simple white swirls in the background and some red/orange berries to tie it all together.
