So this is my first Bethesda game, so this question may sound a bit odd, but i have no clue what i should do now (ingame).

At first this game started a bit hard for a lvl one char without knowledge, but it felt ok. The First two dragon kills were pretty epic also!
After some time it got really hard, so i decided to get some internet help. There I was informed: blacksmithing is the way to go, so I farmed 1h and got some Dragon armor...

This armor was a blast and the beginning of the end... 2hours later of "easy" gameplay i killed Alduin (the endboss?) without much trouble (the second dragon which i killed alone was harder). with the total of ~20hours.

6 hours later of "playing" i realized, i am grinding quests and to the worse, this is not even a challenging grinding... Every opponent the game throws at me is either a one or a two hit.

Is this now the end or will it get a bit harder again?
