I know there already was a critique, but I didn't feel like that was an actual "critique", it was more a free praising of your already well-known skills, so here I go
The idea is indeed most original, I am disturbed by some things of it though: first, the bottom of each pentagram is light blue, and it somehow clashes with the rest of the colours chosen in a way which isn't completely nice, to me. Secondly, the pillars under each pentagram lack the smoothness and the care you usually have for each tiny detail, I think. They don't make justice to the rest of this work's beauty and are a bit poor, maybe.
Also, look at the note descending from the first top pentagram onto the second (which colours go from yellow to greenish), the colour doesn't fill it up correctly, is that a render problem?
Anyway, apart from these, I love how you placed colours and shapes, my friend. As always, your works stun and inspire me.

^{My first critique.}

Vision:
It's just utterly stunning. Anyone passing by this deviation wouldn't be able to hold back a gasp or a stare. The use of 3D here is immense, The contrast and shadows, all used perfectly to give the result of this masterpiece of a deviation. The glass and chromatic effect really does favours on 'Rhythmics'. Needless to say more.

Originality:
After bringing myself back from being awe-struck, I realise how creative this is. A 3D version of written music. Seriously, who'd a thunk it? It's just an amazing idea, to view music in another point of view. The grab what is being born in a musicians head as it flows through her/his hand and onto paper.

Technique:
Of course, I adore and have fallen inlove with the 3D and colourful-glass effect. It gives a sense of pure perfection. The art is more atmospheric and holds more hidden emotion, waiting to be discovered by each deviant that views this. This technique also does wonders for the design, the idea behind creating 'Rhythmics', however. Maybe yu should experiment with smaller ranged colour scheme. I love the colours, I honestly do, but I smaller range could create a bigger result. This is ofcourse, a suggestion.

Impact:
The impact, as said before, is like being hit by a truck. Both concept and execution is 100% perfection. The detail to the coloured glass to the wide range of lighting makes yur heart melt. And to create this available as a wallpaper, we can all have melting hearts together.

^{I apoligise if this critique sounds 'average' and 'dull' but it's my first try. I felt I had to write more than a measly comment to express how I felt about this wonderful piece of 3D art.}
