First of all, welcome to the FC subforum!
You have some really good tags and my favorite is this one
I love the vibrance, the creativity, the typo, pretty much everything
Take away that border and it'd be even better.
As for your work in general, I would suggest watching the contrast on some of your tags. Overcontrasted sigs look good in some cases, but it's easy to go overboard with it. Also don't spam effects like in the 3rd and 4th tags on the left in the OP (although I suspect you've already gotten past this as those look like older works).
Amazing work in general and keep it up!
