nice sig! I like the effects. Text stands out to much tho.. I wouldn't do that black stroke! Also I am personally not a fan of colored borders. Black or white borders work best imo. You might try to blur more parts in the bg and on the sides of your sig to create more depth.
Nice looking tag here brah.
But try working on the lighting you got going here. It looks to strong IMO so tone it down a bit ghee.
Also seems too messy. I'd probably erase some of the effects on the right corner. Seems unnecessary and the effects around the render look nice and those effects take away from it.
KIU brah
