I was attracted by this piece as soon as I saw it in my devwatch. Not only because it's blue, but because it has that simple clarity which does not leave out richness of details, that I so love in abstract art.
Let's begin with the placement of the sphere, which is the most lovely thing. It gives the piece an element of discontinuity, that at the same moment underlines simmetry (the same thing happens in the right half of the image, where the lines are broken, but the shapes are maintined). The glow at the top of it makes it seem like there is a distant sun shining on this fractal. The shadow the sphere is throwing gives the impression that the sphere itself is some kind of satellite eclipsing the cold sun.
Overall the piece shows a lovely use of the rule of thirds. The use of different shades of two complementary colours like blue and orange strenghten the composition. The textures given by the differently spaced lines, create a beautiful three-dimensional effect, that gives movement and life to this work.
It could be considered a bit dark, but I think that adds to the general mood. Even if I'm not a fan of borders in fractal art, this time the border is not invasive nor bold, and enhances that 3d feeling I mentioned before.
I find it extremely difficult to point a flaw in this work. Maybe, at the center of the squared shapes, I could use a bit more of oranges and get rid of that green, or at least turn it more towards the blue spectrum, but I'm just being picky, here.
As if the ball and the shade it drops weren't enough, even the central vortex adds a lot to its tridimensionality. It's been split very well too, and I also like the gradient and the light white blur on the ball. Gg!
