On this first one I used Sakura's gelly roll MOONLIGHT pens in blue and light green. I went back and covered a triangle shape in black over the top....love the dramatic look to doing that!
Then I tried a Sakura gelly roll METALLIC pen in gold. I found that it was hard to cover the the Metallic pen with black, so I went in with the gold pen and outlined the black area.....kind of like that.
I really liked how the Metallic pens sparkled and illuminated the black tiles, so I did another one with a lot of different colors. I did not blacken any areas, but I added some little puffs to some of the tips with the Zenstone.
All three side-by-side.....
