It looks lovely to me. How did you color this one? There are lots of ways!
Blue is a sharpie. The red is an acrylic paint.
High flow Golden paint is my favorite probably to use with these, I flood the tile surface and squeegee it around until it absorbs in, then wipe with windex & paper towel. The metallics give you some lovely effects too!
I especially like it with the compass.
oooh, very nice!
