Here's another sample I came up with last night using a micron pen on top of stamped images. It's really mindless to doodle and it's actually pretty relaxing.
The stamp set I used is called "Crazy about You" and is found in the current mini catalog. The ink colors are Melon Mambo, Daffodil Delight, Perfect Plum and Old Olive. I popped the sentiments up on dimensionals.
Go try it!
