I think you have one of the nicer blue chips i've yet seen....the others are very nice as well.
Go take a look at these ASM chips if you need some edge spot and color guidance....CNC posted a chart of colors as well as one of my pictures to show some real life chips.

My opinion on the green chip is that it needs more contrast...try arc yellow and pink instead of dg yellow and green.
The black chip is elegant, but I personally like color in one of the edge spots.
Then for the yellow chip, look at the Palmas $5000 in the picture...try a yellow base with black and lavender. You can see these colors on the INHD poker show which is on TV Sunday afternoons from the Plaza in LA.
The blue, red and brown chips are stunning color combos and not really in need of more work if you like them...
