The fractals seem a bit........idk how to say it but they don't really flow well together as they should. Pick either flame sparks or the stellar kind to use at a time. they kinda clash a bit. Also mess around with blurring. it gives the illusion that some items are in the far distance and brings depth to the sig like this one should. And try not to hide the text that much. Give it a bit more attention, but not so much as to overpower the look you are going for/. Good work otherwise. 6.9/10 for me.
Better yes. Try to add that detail to your works if you have backgrounds that seem like they deserve to look like they're in the distance. Or do it for the hell of it for the depth illusion
like 6.5-7 I'm not a huge fan of the size you made it and also the text is both unfitting and positioned poorly. Adjust the size of the signature as a whole and maybe the text as well and it'll be really nice.
