Electric pulse - has it all, interesting shapes, good catch title which is leading you to believe you visiting either a micro-cosmos or even somebody's neural pathways. I like the blue-electrifying effect of living tissue. The flow of thought, the flow of life. The grey in the gradient might be serving the right purpose here, even if it comes out a bit dull - the grey matter perhaps. The tilt is a bit off to my visual conception I would have rotated it maybe 10-15 deg to the left, improving the angle. Well there is always a lot of experiments to be done after you apo finishes render, to bad the post-processing allows limited access. Interesting concept overall and the pulse is flowing into my faves.
