This image has some good possibilities. You've really got good depth and symmetry going on, I'd like to see a little sharper contrast with the shades of blue, going almost to a blue-black. Just a thought...
This image constantly shifts in my mind's eye ... and that is a good thing.
At first glance the colour palette makes it appear, at least to me, more 2-D. Than as I look and view more, the shapes start to transform this illustration into a very intricate maze of corridors and beams of light.
I don't know if you will appreciate this particular descriptor, but, this is rather 'beautiful' in my mind. Nice work and yes, keep on, keeping on with the experimentations.
