The short answer is "no." I recommend maxing the difficulty though, at least so that you can't one-shot EVERYTHING. I rolled the same build as you on my first playthrough, and by level 40 I had a full set of legendary, double-enchanted dragonscale armor, a legendary, double-enchanted daedric bow, and double-enchanted ring/amulet. At that point, the only thing left to do was finish all the major quest chains, explore until I got bored, and then kill every living thing in the game (although it stupidly refuses to let you murder certain NPCs). That last part was just about the most fun I've had playing Skyrim or any other Elder Scrolls game (second only to going on a similar murderous rampage in Morrowind after exhausting all other options, but in that game they actually let you kill every single living thing).
