Paint Party Friday: Painting Stamped Images

I've been working on a series of ATC's featuring elements from the periodic table (click on the ATC tag below for details and other examples). This one is Thallium, an extremely toxic substance known as "inheritance powder" because it was commonly used to poison people during the mid-1900's.
I used my twinkling H2O's to color in this stamped image. I've never been very good at using markers to color in stamped images (and refused to go down the copic marker rabbit hole of consumption), but I'm pretty happy with how these work. I think I'm just more comfortable with a paint brush in my hand than a marker.  I also like using radiant pearls, but they take too long to dry. Linking up to paint party Friday and asking does anyone else use any type of paint to color stamped images?
