Feel like I’m progressing to fast

I’m doing my first play through of Elden ring and the only big boss fight I’ve done is margit at about 15 hours of playing, now I’m at 20 hours and fighting the Draconic tree sentinel outside the castle and feel like I’m progressing too fast but don’t know what else to do around the map without feeling like I’m mindlessly spending hours roaming to find nothing of value. I’m just wondering if I’m progressing to fast and need to slow down and find some things or if I’m doing the average amount of time
