Hey Regulus,
Looking cool. There are four things I would consider, though:
Make the actual fuse white, then it looks a lot clearer what is going on up top.
Move the light source off a bit to one side. Having it directly above looks a little weird
Take down the hue shifting. I know little about colors so I can't help you much, but maybe someone else can edit or explain what to do with the colors
Maybe nix the dithering. If you are trying to give it a specific texture, then the current dithering isn't quite working. If you just want it smooth and shiny then no dithering, buit if you want it furry or rough, then you need to use dithering smartly, not just one line along the border.
It is really good that you are experimenting with colors and textures and stuff. Keep up the good work.
