Please zoom your images to between 100 and 200% to inspect. The first image displays a double edge at the point of highlights at the lower right segment of the large circle, and at the top round tip, one of which appears to be blown out by the highlight leaving the ghost edge.
The second displays very bright color fringing at the edges.
In addition the images are quite blurry.
Also with the first one: the footer is kind of strange, which makes the image less usable.
In all: nice abstract representations of something I cannot determine what it is...
I am new here but this looks like a nice community. Not a pro either, but happily willing to collaborate with humble and respectful opinions.
In general I can see blurry edges, perhaps trying to sharpen the image might help. Apart from that, I love them! the one with colors is amazing!.
It looks like a really tiny one piece mechanism, probably?
