D-did you draw all of the lines yourself...!?? surely that isn't a texture. It reminds of some drawings with black paint over an page filled with colours from crayons... and then you'd scratch the paint off with a toothpick to make a multi-coloured lineart!
...But really, my brain can barely process that a human being could've done something so small, so intricate, so detailled!!! That being said, I love the fluo/toxic colours and the hourglass-shaped composition. So inspiring!
