This is the critique you requested on #ProjectComment

The colour scheme is exotic and pleasant; it instantly brings focus to the details. I also like that the palette is carried through to the little squiggles that make up the metallic texture for the farthest background.

Since the focus is so heavy on design, I feel you could make your work shine by zoning in on accuracy, as perfect as you can get it.

There are some portions here and there that don't quite measure up, and coloured areas that aren't quite so neatly filled in, especially the black elements.

Here is where a compass and ruler can be abused to the fullest!

For example, the darker blue diamond shapes on the outermost ring of "petals" could be made by first creating a light "guide" using a compass, measuring halfway through the length of those blue petals. Then a ruler can be used to run guides down the centre of each petal, dividing their width. Now it's all a matter of doing a little math, find the common denominator between the halfway length and width of each petal, so you can use a compass to create the curved lines of those diamonds.

I have always found that getting the geometry right makes up most of the fun in creating these designs. The other joy comes from creating something near-perfect using good old-fashioned tools, and one's own two hands.

Hope this was helpful to you!
