Welcome I have taken TKD in the past. It's a good style and you can get some great kicks out of it. I know when I made the switch to kick boxing then krav maga they said I had some of the hardest kicks the ever felt when the were holding a shield for me during drills. You could keep doing it but you have to have something supplement it like wrestling BJJ some basic boxing.
Best of luck to you.
